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)
