docs(hass): W1N-238 — scribe config split to scribe.yaml + templates/ merge include

- Scribe 3.8.0 block moved verbatim from configuration.yaml to
  /homeassistant/scribe.yaml (scribe: !include scribe.yaml); YAML stays
  authoritative, import semantics unchanged.
- template: switched to !include_dir_merge_list templates; new
  quick_sensors.yaml scaffold (top-level list, quick_ prefix, unique_id
  required; pure sums stay min_max per W1N-233).
- Verified post-restart 2026-08-29 20:19 CST: core check ok, scribe
  connection on, states_written 18581→19426, template entities = 12,
  no scribe/template log errors. Backup configuration.yaml.bak-20260829-201724-w1n238.

+### Config layout: scribe.yaml + templates/ merge (W1N-238, verified 2026-08-29)
+
+- `configuration.yaml` line 29: `scribe: !include scribe.yaml`; line 9:
+  `template: !include_dir_merge_list templates`. No `packages/`.
+- `scribe.yaml` (config root): the Scribe block, content identical to the
+  former inline one; import semantics unchanged.
+- `templates/`: `csg_sensors.yaml` (12 template sensors, top-level **list**)
+  + `quick_sensors.yaml` (scaffold for Quick-derived `quick_*` sensors, empty
+  list with convention header). **`!include_dir_merge_list` merges per-file
+  lists; non-list files are silently skipped** — every file in `templates/`
+  must be a top-level list (`- sensor:` blocks). Directory include only picks
+  up `*.yaml`, so the `.bak` / `.pre-*` backups in the dir are ignored. After
+  adding sensors, verify template-platform entity count = 12 + N (entity
+  registry `platform: template`).
+- Convention (per review + W1N-233): pure sums/averages stay min_max helpers
+  (e.g. `sensor.dang_qian_zong_gong_lu`); only template-logic derivations
+  (ladder pricing, cross-entity conditions) go into `quick_sensors.yaml`.
+- Post-change verification 20:19 CST: `ha core check` ok, 92 s restart
+  (2026.8.3), `binary_sensor.scribe_database_connection` on,
+  `scribe_states_written` 18581→19426 growing, template entities still 12,
+  csg sensors numeric, no scribe/template log errors.
