- Improved logging for delete events in handle-delete.go, including detailed information about the event and its tags. - Added checks for admin and owner deletions, with appropriate logging for each case. - Updated HandleEvent to process delete events more robustly, including success and error logging. - Introduced a new fetchEventById function in nostr.js to verify event deletion. - Updated App.svelte to handle event deletion verification and state management. - Changed favicon references in HTML files to use the new orly-favicon.png. - Added orly-favicon.png to the public and docs directories for consistent branding.
