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
