Add a "Forgot your password?" flow off the login page. A 24-hour
reset_password token is emailed on request, the landing page lets the
user pick a new password, and all other tokens for the user are
revoked on success.
The request endpoint returns the same flash regardless of whether the
email matches a user so that attackers can't enumerate accounts.
Centralized the From and Reply-To headers in Microwaveprop.Mailer.apply_defaults/1
so UserNotifier and EditNotifier can't drift. Drops the EMAIL_FROM env var
override — both values are hardcoded now.
Generated Accounts context, User schema, and controllers via
phx.gen.auth. Adapted it for password-only login with required
email confirmation:
- Users have callsign (unique, uppercased), name, email, password
- Registration form fields: callsign, name, email, password, confirm
- Magic-link login path removed; login is email + password only
- After register, a confirmation email is sent and login is blocked
until the account is confirmed via the token URL
- Confirmation link logs the user in on first use
- SMTP2GO configured as the outgoing mailer in k8s prod
