Add database persistence to 8 edge functions

Implement Phase 1 by adding error span logging and database persistence to 8 edge functions that already log errors:
- detect-location
- export-user-data
- notify-moderators-submission
- novu-webhook
- send-escalation-notification
- send-password-added-email
- resend-deletion-code
- merge-contact-tickets

This update introduces startSpan/endSpan and logSpanToDatabase usage in catch blocks to ensure errors are recorded in the monitoring database.
