Bug fixes:
• Staff should no longer appear to duplicate on the center overview.
• Note timers (Rest, Nutrition and Toilet) should now be restored after tapping Center Overview or resuming the app.
• The class view now automatically syncs timer data when you enter a classroom with a brief "Syncing timers..." indicator.
• Editing a note timer's duration will now update the timer on the device.
• Miscellaneous bug fixes.

*NEW*
We've added a number of quality of life improvements to all notes, and some enhancements to notes with active timers.
• Editing a note now shows the student's avatar, name and age at the top of the edit dialog.
• Saving a note now shows a "Saving" state on create, update or delete.
• If creating, updating, or deleting a note fails, the note form will display an error banner with a description of the issue.
• Rest note editing has been moved to a dialog for consistency with other note types.
• Rest note form now includes an Additional Notes field on both create and edit.
• Completed rest notes now display Scheduled vs Actual duration when editing.

Notes with Timers (Rest, Nutrition, Toilet)
• When viewing notes, if there's an active timer, a banner displays the status. For Toilet and Nutrition notes, this shows the time remaining. For Rest notes, this shows the scheduled wake-up time. If a timer expires, the banner will indicate it.
• When editing a note with an active timer, a banner will display at the top of the form.
• When setting a duration on a rest note, any changes to the start time or duration will update the "Nap will end at X:XX" message in real time.

Timer Behavior:
For Toilet and Nutrition notes, only one timer can be active per student at a time. Creating a new note will either replace the active timer (if the new note includes a timer) or clear it (if it doesn't).

What's New:
• Error banners on note forms when save fails
• "Saving" indicator on all note actions
• Student info shown on note edit dialogs
• Timer banners on Rest, Toilet & Nutrition notes show active/expired status
• Editing timer duration updates immediately
• Class view syncs timers on entry

Fixes:
• Staff should no longer duplicate
• Note timers will restore on center refresh or app resume
• Miscellaneous bug fixes
