refactor: Update Note and Category models to use 'id' instead of 'uuid', and adjust related database operations

- Changed 'uuid' to 'id' in Note and Category models for consistency.
- Updated database operations in NoteRepository to reflect the new 'id' field.
- Modified sync models to accommodate changes in Note and Category structures.
- Adjusted the handling of notes and categories during synchronization.
- Refactored the note editor and home screen to use the new 'id' field.
- Ensured that the 'isDirty' flag is properly set and utilized across models.
