remove email verification temporarily (#6366)

## Summary

- Temporarily remove email verification. After susbcription gating was
enabled, this is less important
- Will re-add the logic back at a later time, defering requirement until
time to subscribe
- For time being, typo emails can be resolved through custom service
(https://support.comfy.org/hc/en-us/requests/new?tf_42243568391700=ccloud&tf_123456=X)
- Keep the route and redirect for deprecation. Not really needed since
the server falls back to root route anyway but generally good practice
and is more resistant to future changes + avoids a single extra routing
step in that scenario.
