chore: Sync users to Resend after email verification (#98)

## Summary
- Changed `SyncUserToResendListener` to listen to the `Verified` event
instead of `Registered`, so contacts are only created in Resend after
the user verifies their email address
- Updated corresponding tests to use the `Verified` event

## Test plan
- [x] `SyncUserToResendListenerTest` passes with `Verified` event
- [x] All auth and listener tests pass
