feat(platform): migrate bot admins from config.yaml to database (#2289)

* feat(platform): migrate bot admins from config.yaml to database

- Add BotAdmin ORM model (bot_admins table) scoped per bot_uuid
- Add Alembic migration 0007 to create table and migrate legacy config admins
- Remove top-level admins key from config.yaml template
- Add GET/POST/DELETE /api/v1/platform/bots/<uuid>/admins endpoints
- Update cmdmgr privilege check to query bot_admins table (bot-scoped)
- Add BotAdminsPanel frontend component in bot detail sessions tab
- Add i18n keys (zh-Hans, en-US)

* fix(ci): ruff/prettier format, fix test_importutil assertion

* fix(ci): prettier format BackendClient.ts and i18n locales

* fix(ci): eslint-prettier fix BackendClient.ts single-param formatting

* refactor: move admin management into session monitor, fix session_id enum format

- Remove standalone admins tab, replace with BotAdminsDialog in session monitor
- Add admin toggle button inline in chat header next to Active status
- Add BotAdminsDialog component with useBotAdmins hook
- Fix session_id written as LauncherTypes.PERSON_xxx instead of person_xxx
  (monitoring_helper.py x4, pipelinemgr.py x1 missing .value on launcher_type)
- Fix duplicate platform/person label in session list and chat header
- Migrate existing malformed session_id records in DB
