feat: add passkey authentication and enhance user preferences

- Add passkey login security event type with fingerprint icon
- Include request and site context in email confirmation for backend
- Add user_id exact match filter to prevent incorrect user lookups
- Enable PATCH method for updating user preferences via API
- Add moderation_preferences support to user settings
- Optimize ticket queries with select_related and prefetch_related

This commit introduces passkey authentication tracking, improves user
profile filtering accuracy, and extends the preferences API to support
updates. Query optimizations reduce database hits for ticket listings.
