- add DialogDescription (sr-only) to EventDialog to satisfy Radix UI
aria-describedby requirement and silence the React console warning
- add htmlFor/id pairing to the all-day checkbox label in EventDialog
- add id and name attributes to all raw form fields (textarea, checkbox)
in event-dialog to resolve biome a11y lint warnings (4 fields fixed)
- add name attribute to hidden file inputs in image-picker and ics-file-picker
- generate public/icon-192x192.png and public/icon-512x512.png so the PWA
manifest no longer returns 404 for the app icons
