Update Oneoff Event

Update one-off daily event completion for a user.

Authentication methods:

1. Regular user auth via Bearer token
2. Admin auth via X-API-Key and X-User-ID headers

This will update the last_oneoff_daily_event timestamp and trigger streak calculation. Uses user's timezone from current_user if available, otherwise queries user_info table.

Query parameters:

• restore: If true, restore a broken streak by incrementing the last active streak instead of starting fresh.

Request body (optional):

• useFreeOffer: If true, increment the free_restore_count when restoring.
• txnId: Transaction ID if the user paid for the restore.
