VPS-90: clarify CSG prediction estimates

- 安装 card-mod (HACS)，用 CSS `ha-card { height: Npx }` 强制等高
- 饼图+人体感应 520px，温湿度双图 520px
- 饼图图例从底部移到右侧 (legend position: right)，高度 510→520
- 关键认知：apexcharts chart.height 含图例，timescale-plotly height 是纯绘图区
- 提交 scripts/ha-ws-client.py (纯 stdlib WS 客户端，文档已引用)

+才退回 `csg_30d_avg`。**动机**：本月至今速率按天数爬升可信度，避免月初被上月污染；
+近 7 日速率兜底，因为月初唯一的新数据就是上月末。Block C 触发器加

+- **Quick 面板改造 + timescale 卡两个真 bug 修复 (2026-09-21)**：起因是用户
+  觉得「面板标题 + 统计方式」不对劲。只读审查查出三个问题并全部修掉：
+
+  **① 卡 JS：`<n>d` 档实际渲染成 n 小时（VPS-92 的扩容其实没生效）**。
+  非 energy 档走 `const hours = parseInt(this._selectedRange) || 24;`，
+  `parseInt("7d") === 7`。全卡唯一能解析 `d` 的 `parseDurationToMs()`
+  （正则 `/^(\d+)(m|h|d)$/`）**只被 `resolveEnergyWindow()` 调用一次**，
+  即只服务 energy 卡。后果：`3d` 比 `24h` 还短（3h），`14d`→14h、`30d`→30h。
+  **修复**：改用 `Math.max(1, parseDurationToMs(...)/3600000)`；顺带把采样密度
+  目标 80 → 160 点（7d 档从 2.1h/桶降到 1.05h/桶）。备份
+  `.lovelace-backups/timescale-plotly-card.js.bak-20260921-pre-dayfix`。
+  实测（本地 node 跑卡里的 `parseDurationToMs`）：`3d→72h / 7d→168h /
+  14d→336h / 30d→720h`，各档均 ~160 点；`node --check` JS 语法 OK。
+  **资源 URL 已加 `?v=20260921` 强制浏览器重取**（原来无 hacstag，缓存问题会
+  让修复「看不见」）。
+
+  **② 功率卡画的是瞬时采样而非统计量**。reader 对 `table=sensor_minute`
+  （时间列名 `minute`）默认 `downsample_method = "last"`
+  （`custom_components/timescale_database_reader/__init__.py` L385-389），
+  即每桶取「末一分钟的瞬时值」。实测空调 1 小时桶：03:00 真实均值 241.6 W /
+  峰值 1128 W，图上只画 157；19:00 真实均值 97.6 / 峰值 676，图上画 **13**
+  （看起来像停机）。因 `sensor_minute` 已是均匀 1 分钟 LOCF 序列，`avg()`
+  才是正确时间均值。**修复**：两张功率卡加 `downsample_method: "avg"`。
+  **用电量卡不用改**——累计计数器配 `last()` 就是桶末读数，卡片再 diff，
+  本来就是对的；人体感应卡显式 `last` 对分类信号也对。
+
+  **③ 标题与分组名不副实**。按 7d 实测（峰值/均值）重分组并改名：
+  | 位置 | 改前 | 改后 |
+  |---|---|---|
+  | 分区 | 大功率电器 | **峰值负载**（厨房电器 1839 / 空调 1128 / 电水壶 957 / 咖啡机 882 / 电脑 363 W） |
+  | 分区 | 常驻负载 | **基础负载**（主网络 75 / 冰箱 137 / 大房 290 / 水设备 171 / 无线AP 976* W） |
+  | 分区 | 用电 | **今日用电** |
+  | 分区 | 灯 + 开关（分开在最顶和最底） | **灯与开关**（合并置顶，可操作项集中） |
+  | 分区（新） | — | **此刻耗电** |
+  | 徽标 | 总功率 | **插座合计**（只是 9 个插座之和，不含灯/换气） |
+  | 实体 | 迷你 / mini数显 / 数显 | **卫生间 / 客厅 / 卧室**（HA area 本来就有，之前用的是设备型号名） |
+  | 实体 | 电池(移动) | **厨房(电池)**（该设备 area 也是厨房） |
+  删除 3 张与分区标题重复的卡 title（用电量(按插座) / 室内外温湿度 / 活动状态）。
+  \* 无线AP 7 天里只有 2 分钟 >150 W 却记到 976 W —— 单点毛刺，会把 y 轴顶飞，
+  待查。
+
+  **④ 新展示**：新增「此刻耗电」区 = `custom:apexcharts-card` **donut**，11 个
+  插座当前功率（`graph_span: 10min` + `update_interval: 1min`），回答「现在什么
+  在吃电」；环境区拆成**室内外温差**（新模板传感器 `sensor.quick_wen_cha` =
+  3 个室内温度均值 − 室外，画零线上下 fill）+ **湿度**（4 条），4 个温度进徽标。
+  传感器加在 `templates/quick_sensors.yaml`（W1N-238 约定的落点，顶层列表，
+  `quick_` 前缀 + unique_id），非 trigger 型模板卡，**`template.reload` 即可生效，
+  无需重启 Core**（实测 `POST /core/api/services/template/reload` → 200，
+  `sensor.quick_wen_cha` = 3.9 °C）。备份
+  `templates/quick_sensors.yaml.bak-20260921-pre-wencha`。
+  最终分区顺序（按「可变性」）：灯与开关 → 此刻耗电 → 今日用电 →
+  峰值负载(2) → 基础负载(2) → 环境 → 人体感应。
+
+  **⑤ Quick 布局重构 (2026-09-21 晚)**：用户反馈饼图（apexcharts donut）撑满
+  整行（span 4）且不满、马桶换气开关 tile `columns: "full"` 占满整行太宽、整体
+  布局需要重新思考。改动：
+
+  **布局重排**（阅读流：控制 → 此刻 → 趋势 → 今日 → 环境）：
+  | 行 | 左 (span 2) | 右 (span 2) | 主题 |
+  |---|---|---|---|
+  | 1 | 灯与开关 (span 4) | | 可操作项置顶 |
+  | 2 | 实时功率 (donut) | 人体感应 | 「此刻状态」 |
+  | 3 | 峰值负载 | 基础负载 | 「功率趋势」（原配对保留） |
+  | 4 | 今日用电 (span 4) | | 11 条堆叠柱需要宽度 |
+  | 5 | 温湿度 (span 4) | | 温差+湿度两图并排 |
+
+  **标题改名**：此刻耗电→**实时功率**（与峰值负载对仗）、环境→**温湿度**
+  （更具体）。删饼图卡内冗余标题 "各插座当前功率 (W)"。
+
+  **开关收窄**：马桶换气电源 tile 从独立 `columns: "full"`（48 列全宽）→ 移入
+  灯的 2 列嵌套网格第 5 格，与灯卡等宽（半行）。
+
+  **饼图高度**：`apex_config.chart.height` 280→350（11 项底部图例占 ~100px，
+  280 时饼图本体太扁）。
+
+  **⑥ card-mod 等高 (2026-09-21 晚)**：不同卡类型（apexcharts vs timescale-plotly）
+  的 `height` 渲染比例不同（apexcharts 含图例/内边距，timescale 是纯绘图区），
+  直接对齐数字无法视觉等高。安装 **card-mod**（HACS → card-mod + card-mod-studio）
+  后用 CSS 强制 `ha-card` 高度：
+
+  ```yaml
+  card_mod:
+    style: "ha-card { height: 520px !important; }"
+  ```
+
+  **最终高度**：饼图+人体感应 = **520px**，温湿度双图 = **520px**。其余图表
+  （峰值/基础负载 280、今日用电 320）保持各自原生高度，不强制统一——不同图表
+  类型适合不同高度，强行统一反而让简单图表显得太空。
+
+  **关键认知**：apexcharts `chart.height` 包含图例区域，timescale-plotly `height`
+  是纯绘图区。同一数字渲染出来 apexcharts 视觉上更矮。card-mod 直接控制
+  `ha-card` 容器高度，绕过内部渲染差异。
+
+  备份：`.lovelace-backups/dashboard-quick-20260921-pre-titles.json`（同日早期
+  备份，覆盖标题+布局全部改动的回滚）。
+
+  **验证**：`ha core check` OK；WS 读回与写入 payload **逐字节相同**；
+  新配置引用的 **40 个实体全部存在**且无 unknown/unavailable；
+  卡 JS `node --check` 通过、时长解析实测正确。
+  **改法（可复用）**：写 Lovelace 配置必须走 WS
+  `lovelace/config/save`（**勿直改 `.storage/`**）。本机 python/HA 容器内经
+  supervisor 代理连 WS 会被 loop-prevention 拒；可行路径是
+  `docker run --rm -i --network host -e SUPERVISOR_TOKEN --entrypoint python3
+  r.hassbus.com/home-assistant/aarch64-hassio-supervisor:<ver> -c "..."`
+  跑本仓库的 [`scripts/ha-ws-client.py`](../scripts/ha-ws-client.py)（纯 stdlib，
+  不依赖 websockets/aiohttp，也不依赖 `-v` 挂载——`-v /tmp/...` 会落到 Docker 宿主
+  而不是 SSH add-on 的 `/tmp`）。读配置：`{"action":"get","url_path":"dashboard-quick"}`；
+  写：`{"action":"save",...,"config":{...}}`。备份
+  `.lovelace-backups/dashboard-quick-20260921-pre-titles.json`。
+
+  **回滚**：还原 `dashboard-quick-20260921-pre-titles.json`（WS save）+
+  `timescale-plotly-card.js.bak-20260921-pre-dayfix` + 删 `quick_wen_cha`
+  （还原 `quick_sensors.yaml.bak-20260921-pre-wencha` + `template.reload`）。
+  改了卡 JS 就要把资源 URL 的 `?v=` 再 bump 一次。

+### Web UI (from laptop / WSL)
+
+```bash
+curl -4sI https://repo.windy.me/ | head -3        # expect HTTP/2 200
+echo | openssl s_client -connect repo.windy.me:443 -servername repo.windy.me 2>/dev/null \
+  | openssl x509 -noout -dates                     # expect LE cert not expired
+```
+
+### Git SSH (the critical check)
+
+```bash
+ssh -F /dev/null -o BatchMode=yes -p 2222 git@repo.windy.me 2>&1 | head -2
+```
+
+Expect `Hi there, windy! You've successfully authenticated …` and no shell.
+Login user **must be `git@`** (`windy@` fails: publickey denied). Clone URLs
+need the owner segment: `ssh://git@repo.windy.me:2222/windy/<repo>.git`.
+The host key is the reused Soft Serve ed25519 key (fingerprint prefix
+`SHA256:PdxZRe74…`) — a changed fingerprint means someone rotated it.
+
+### Registration / hardening (server-side, definitive)
+
+```bash
+ssh -F /dev/null -4 windy@us2.wsvc.info \
+  'grep -E "DISABLE_REGISTRATION|INSTALL_LOCK" /opt/gitea/config/app.ini; stat -c "%a %U" /opt/gitea/config/app.ini'
+```
+
+Expect `DISABLE_REGISTRATION = true`, `INSTALL_LOCK = true`, file mode `600`.
+
+### Backup freshness
+
+```bash
+ssh -F /dev/null -4 windy@us2.wsvc.info 'tail -4 /opt/gitea/backups/backup.log; ls -lt /opt/gitea/backups/ | head -4'
+```
+
+Expect a `Backup OK` line from today's 02:00 run (products include
+`app.ini.tar.gz`, `gitea.db`, `repos.tar.gz`) and ≤ 14 retained sets. A
+backup set older than ~25h with no log error means cron silently died —
+investigate before proceeding.
+
+### Logs and memory gate
+
+```bash
+ssh -F /dev/null -4 windy@us2.wsvc.info \
+  'docker logs gitea --since 24h 2>&1 | grep -iE "error|panic" | tail -5; free -m | head -2'
+```
+
+Expect no recurring errors (single SSH auth-failure warnings from the
+Traefik proxy IP are background noise) and `available` ≥ 150 MB
+(VPS-94 memory gate; gitea idles ~400 MB RSS).
+
+## Safety
+
+- Read-only: never mutate configuration or service state during this check.
+- If live state conflicts with an expected value (wrong digest, HTTPS
+  non-200, stale backup, registration enabled, `available` < 150 MB),
+  `STOP` and report per repo rules.
+
+## After config changes
+
+`/opt/gitea` has no Ansible coverage yet. Reviewed changes
+(compose edit, digest bump) are applied manually and verified:
+
+```bash
+ssh -F /dev/null -4 windy@us2.wsvc.info 'cd /opt/gitea && docker compose up -d && docker compose ps'
+```
+
+Then re-run the diagnostics above. Keep [compose/gitea/](../compose/gitea/)
+in sync (reference copy, server files win).

+"""Stdlib-only Home Assistant WebSocket client (via the Supervisor core proxy).
+
+Why this exists
+---------------
+Some HA operations have **no REST route** and must go through the WebSocket API
+-- writing Lovelace config (`lovelace/config/save`) is the main one, and the
+`.storage/` files must not be hand-edited (HA may overwrite them, and edits skip
+validation). The obvious paths are dead ends on this host: the HA host and the
+core container have no usable WS client (the Supervisor proxy rejects core's own
+loop), and the Supervisor image has neither `websockets` nor `aiohttp`.
+HA's WS protocol is plain text frames, so ~90 lines of stdlib is enough.
+
+Run it from the HA host (see hosts/hass.windy.lan.md "改法（可复用）"):
+
+    B64=$(base64 < scripts/ha-ws-client.py | tr -d '\n')
+    echo '{"action":"get","url_path":"dashboard-quick"}' | \
+      docker run --rm -i --network host -e SUPERVISOR_TOKEN --entrypoint python3 \
+        r.hassbus.com/home-assistant/aarch64-hassio-supervisor:<ver> \
+        -c "import base64,sys;exec(base64.b64decode('$B64').decode())" - -
+
+Do NOT use `-v /tmp/...`: that path is resolved by the Docker daemon on the
+HAOS host, not inside the SSH add-on, so the mount comes up empty.
+
+Payload / output
+----------------
+    {"action":"get",  "url_path":"dashboard-quick"}
+    {"action":"save", "url_path":"dashboard-quick", "config": {...}}
+    {"action":"raw",  "command": {"type":"lovelace/resources/list"}}
+
+    python3 ha-ws-client.py <payload.json|-> <out.json|->
+
+"-" reads the payload from stdin / prints the result to stdout, wrapped in
+<<<DSH_RESULT>>> / <<<DSH_END>>> markers so it survives the add-on login banner.
