Enhance delete event handling and logging

- 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.
