loadNotes() crashed entirely if IndexedDB was unavailable because
getAllNotes() was called outside try/catch. Non-OK API responses
(401, 500) were silently ignored across loadNotes, createNote, and
sync operations — users saw empty data with no feedback.
Changes:
- Wrap all IDB calls in try/catch so the app works without IndexedDB
- Show toast on non-OK API responses in loadNotes and createNote
- Redirect to /login on 401 responses
- Make sync pull/push resilient to IDB unavailability

- Bump IDB version to 2, add pendingAttachments object store with noteId index
- Add CRUD helpers: addPendingAttachment, getPendingAttachments, removePendingAttachment
- ImageUpload stores blobs in IDB when offline, displays via blob URLs
- Show pending sync indicator (RefreshCw icon) on not-yet-uploaded images
- Add pushPendingAttachments to sync client, runs after note push
- Pending attachments auto-upload on reconnect via existing online event listener

Load notes from IndexedDB first for instant display, then sync from
server in background. All mutations now persist to IDB when online,
keeping the cache always current. Eliminates empty state flash on load.

- Extract toast store to standalone module so notes store can show toasts
- Add try/catch to all note mutations with optimistic updates + IDB queue on network error
- Wire up startSync/stopSync in layout to enable online/offline event listeners
- Reload notes from server after successful sync push to prevent data loss
- Connect SyncIndicator to real sync status with Lucide cloud icons
- Add 300ms minimum display time for status transitions
- Add e2e tests for offline create, edit, trash, and sync-on-reconnect
