- Fix missing await in pets API route causing empty responses
- Fix updateSetting to use upsert pattern instead of update-only
- Create missing /api/admin/sounds/upload route (upload was broken)
- Wire bulk delete actions in catalog table
- Replace native confirm() with useConfirmDialog() across rooms and clone pages
- Add error logging to silent catch blocks in radio actions and audit route
- Add graceful degradation to devops health endpoint
- Add cache eviction to clone icon route to prevent memory leak
- Internationalize hardcoded Italian strings to English
- Remove placeholder created_at fields from prefix API responses
- Remove dead code and fix type errors in translations and import pages
- Standardize PERMS import path in analytics export route
