rock 701d79deac feat(iam): deliver ZITADEL notifications through Gotify
ZITADEL sends verification codes and password resets by SMTP only, and this
cluster has no mail path. Every human user therefore sits at
verified_email = empty and can never finish a first login, at ZITADEL or at
Forgejo.

Add an smtp-gotify relay in the iam namespace: it accepts plain SMTP on :2525
and forwards each message to the existing Gotify instance, so codes arrive on
the phone through gotify/igotify instead of email.

Point DefaultInstance.SMTPConfiguration at that Service with TLS off, because
the relay speaks plain SMTP inside the cluster. The relay holds the Gotify app
token in a SOPS-encrypted Secret; values never carry the token.

# SMTP -> Gotify relay for ZITADEL notifications.
#
# ZITADEL sends verification codes, password resets and one-time passwords by
# SMTP only, and this cluster has no working mail path: no SMTP credentials are
# configured for ZITADEL, and the notification table shows
# verified_email empty for every user. Without a delivery path nobody can finish
# a first login, at ZITADEL or at any relying party such as Forgejo.
#
# This relay accepts plain SMTP on :2525 and forwards every message to Gotify,
# so codes arrive on the phone through the existing gotify/igotify setup instead
# of email. ZITADEL then points DefaultInstance.SMTPConfiguration at this
# Service (see k8s/infra/iam/zitadel-values.yaml).
#
# The Gotify token is a Secret, never a literal here.
