feat(agent-office): notification badges + CEO desk document panel + telegram test

- Add notification state management with badge counts in useAgentManager
- Render exclamation badge on agent sprites (separate from status icons)
- Add CEO desk document icon with click-to-open activity panel
- Create DocumentPanel with unified activity feed + per-agent detail tabs
- Add telegram test button to stock agent ChatPanel
- Remove TaskHistory + bottom toolbar (replaced by DocumentPanel)
- Add getActivityFeed API helper
