Pull request overview
This PR fixes race conditions that occur when users quickly switch between notes, which could result in data from one note being saved to or displayed for another note. The fix involves capturing note IDs before async operations and validating that the current note ID hasn't changed after async operations complete.
Changes:
- Added race condition checks in the load() function to prevent setting note data if the current ID changed during the async fetch
- Captured note ID before save operations to ensure content is saved to the correct note even if the user switches notes during the save
- Updated the noteTitle watcher to use note ID instead of route path for better consistency

The noteTitle watcher has a potential race condition. While currentId.value is checked, it's not captured at the time the watcher is triggered. If currentId changes between when noteTitle is recalculated and when this watcher callback runs, the title from one note could be used to update the opened page for a different note. Consider capturing currentId.value at the start of the watcher callback, similar to how savedNoteId is captured in the save function.

Use strict equality (===) instead of loose equality (==) for consistency with the rest of the codebase and to avoid potential type coercion issues.

Fixed autosave and quick tab switching. The note id might not match the id in the url
