Fix session expiry check (seconds vs milliseconds mismatch in raw SQL),
conditionally render app chrome only for authenticated users, use full
page reload after login/setup for proper session propagation, remove
HTML minlength to allow JS validation, fix store to remove notes on
trash/archive, and make auth tests race-condition safe.

- Batch-fetch tags for notes in a single query instead of per-note loops
- Add composite indexes on notes, note_tags, and sync_log tables
- Wrap sync push in a transaction for atomicity
- Replace O(n) cleanExpiredSessions with single DELETE query
- Use SQL WHERE in getChangesSince instead of loading all notes
- Extract shared syncNoteTags utility to eliminate duplication
- Add root +error.svelte boundary matching app theme
