Add self-terminating background task for draft timer monitoring:
- Runs every 15 seconds during active draft
- Checks timer status and self-terminates when disabled (resource efficient)
- Sends warnings at 60s and 30s remaining
- Triggers auto-draft from team's draft list when timer expires
- Respects global pick lock (acquires from DraftPicksCog)
- Safe startup with @before_loop pattern
- Comprehensive error handling with structured logging
Task integrates with draft services (no direct API access) and
follows established patterns from existing tasks.
