docs(soft-serve): 镜像固定 v0.12.2 + 备份 sidecar + 非 root 运行 (W1N-244..248)

- 镜像 pinned charmcli/soft-serve:v0.12.2（GHCR 为 dev/nightly 源，无 v0.12.x tag）
- soft-serve-backup sidecar：每日 02:00 sqlite .backup + repos-config 打包，03:00 prune 保留 14 份
- 非 root 运行（user 1000:1000），data chown；ssh.public_url 修复
- compose 源码参考：compose/soft-serve/（服务器文件为准）
