Add Agent Context API for external agent integration

Phase 1: Authentication and read-only context
- POST /agent/auth/request - request access with name + agent_id
- GET /agent/auth/poll - poll for approval status
- POST /agent/auth/approve|deny - user approval (browser auth required)
- GET /agent/context - 7-day timeline context (agent session required)

Phase 1.5: Browser-only agent endpoints (HTML pages)
- GET /agent/web/request - request page with token
- GET /agent/web/status - status page with polling
- GET /agent/web/context - context page with timeline data

WebSocket notifications:
- GET /ws/notifications - push agent requests to browsers
- Approval modal with trust indicators and countdown timer

Database:
- agents table for registered agent tracking
- agent_sessions table for pending/active sessions
