feat(journals): implement force reset for lost passcodes and harden sync

- Added 'Force Reset to Plain Text' button in the editor for decryption failure states.
- Guarded reset functionality with '.edit_mode'.
- Refactored background sync logic to properly isolate 'untrack' calls and prevent content resets.
