fix: use proper PocketBase hook patterns

- Replace unsafe type assertions with safe AuthRecord() method
- Remove unused 'strings' import
- Remove unused ServeEvent struct and binding
- Use proper error response methods (apis.NewForbiddenError)
- Use app.Subscriptions().Broadcast() instead of Realtime()
- Fix hook signatures to return error instead of next function
