Simplify validation, compression heuristics, and notification scheduling (#841)

Browse Source 
* Simplify validation, compression heuristics, and notification scheduling

* Consolidate notification logic and add InputValidator monitoring

Follow-up improvements to address PR feedback:

1. Consolidate notification functions
   - Add interruptionLevel parameter to sendLocalNotification
   - Refactor sendNetworkAvailableNotification to use consolidated function
   - Removes 12 lines of duplicate code

2. Add monitoring to InputValidator
   - Log control character rejections for production monitoring
   - Privacy-preserving: logs length + count, not actual content
   - Uses .security category for proper log routing

3. Add comprehensive InputValidator tests
   - 28 test cases covering validation, control characters, unicode, edge cases
   - Ensures behavioral changes are well-tested and documented
