Updates the password reset page to use the new theme.
Adds new endpoint '/api/v0/auth/reset-password'
for password reset.
Additionally, updates the link-clicking mail simulator to only
click links with a specified attribute. Otherwise, the password reset
cancellation link would be clicked before the password reset link
could be accessed, rendering testing impossible.

Update the forgot password, invite, and welcome emails to be
cosistent with deployed code. This change is part of an ongoing
