feat(config+main): aider-watch v2 settings + router + lifespan register

- Add 4 settings to config.py: AIDER_WEBHOOK_SECRET, AIDER_EVENTS_STREAM_KEY, AIDER_PATTERN_EXTRACT_INTERVAL_HOURS, USE_AIDER_FEEDBACK (ADR-091)
- Import aider_events_v1 router in main.py imports (alphabetical after ai_slo_v1)
- Register aider_events_v1.router in include_router block (after alert_operation_logs_v1)
- Register run_aider_event_processor_loop() in lifespan (after compliance_scanner_loop)
- All 65 tests pass (24 action_parsing + 41 aider-watch tests)
