fix: initialize notes path on app startup to resolve missing default directory (#9728)

* fix: initialize notes path on app startup to resolve missing default directory

- Add notes path initialization in store persistStore callback after rehydration
- Update NotesSettings to sync tempPath when notesPath changes from initialization
- Ensure notes directory is set even when user doesn't visit NotesPage first
- Fixes issue where notes path was empty after data reset until NotesPage visit
