feat(ios): enhance recovery logging and metrics recording

Implement comprehensive logging and observability for recovery operations:

- Add HistoryDAO for Core Data history recording
  - recordRecovery() method with execution time tracking
  - recordRecoveryFailure() method with detailed error info
  - Query helpers for history retrieval
- Enhance DailyNotificationReactivationManager logging:
  - Add execution time tracking (startTime/endTime)
  - Enhanced error logging with NSError details (domain, code, userInfo)
  - Comprehensive logging at each recovery step
  - Missed/future notification count logging
- Implement Core Data persistence for recovery metrics:
  - Recovery execution time
  - Missed notification count
  - Rescheduled notification count
  - Verified notification count
  - Error count
  - Diagnostic JSON with full recovery context
- Update recovery methods to record history:
  - Cold start recovery
  - Termination recovery
  - Boot recovery
  - All with timing and metrics

 ### 7.1 Recovery Logging
 
-- [ ] Add comprehensive logging:
-  - [ ] `DNP-REACTIVATION: Starting app launch recovery`
-  - [ ] `DNP-REACTIVATION: Detected scenario: [scenario]`
-  - [ ] `DNP-REACTIVATION: Missed notifications detected: [count]`
-  - [ ] `DNP-REACTIVATION: Future notifications verified: [count]`
-  - [ ] `DNP-REACTIVATION: Recovery completed: [result]`
-- [ ] Add error logging:
-  - [ ] `DNP-REACTIVATION: Recovery failed (non-fatal): [error]`
-  - [ ] Include error details and stack trace
+- [x] Add comprehensive logging:
+  - [x] `DNP-REACTIVATION: Starting app launch recovery`

 ### 7.2 Metrics Recording
 
-- [ ] Record recovery metrics in history table:
-  - [ ] Recovery execution time
-  - [ ] Missed notification count
-  - [ ] Rescheduled notification count
-  - [ ] Error count
-- [ ] Add diagnostic JSON to history entries
