- Remove unauthenticated /test route that dispatched FetchNostrProfileJob
for a hardcoded user (routes/web.php).
- Enforce created_by ownership check in meetup and lecturer Livewire edit
components; mirror the existing services/edit pattern.
- Replace blind-trust nostrLoggedIn handler with NIP-42-style signed event
verification: server-issued challenge stored in session, client signs a
kind:22242 event, server verifies signature via swentel/nostr-php and
derives npub. Challenge is single-use with 5-minute TTL.
- Validate the ?my[] parameter on the calendar download endpoint as an
array of integers and intersect with the authenticated user's meetups.
