This takes part of the work being done in #96 that was reverted but still useful.
Note Tailwind and Fresh weren't upgraded because there's no security vulnerability in either, and I have found the new versions to be worse in performance. Thos will likely stay at those fixed versions going forward.
This adds Email as a multi-factor authentication method/option. It reuses the `VerificationCode` for the code generation and validation.
It also refactors the email templating for easier repurposing.
Finally, it has a small Deno version bump.
Closes#25
* Add TOTP MFA Support
* Add Passkey MFA Support
It's not impossible I missed some minor cleanup, but most things make sense and there isn't a lot of obvious duplication anymore.
