fix(iam): use the built-in ZITADEL login page

Sign-in failed with "Could not create session for user". The ZITADEL API
logged, on every session call:

  authz: verify access token -> invalid token
  token verifier repo: issuer does not match: Expected
    https://zitadel.riotpiao.com, got: login-client
  zitadel-login: [Password] Could not update session

The hosted Login UI authenticates as the machine user `login-client`. That
user did not exist in this instance, because the chart's setup job creates it
and setupJob is disabled after the first sync. Without the user the UI cannot
write a session, so no one can sign in, at ZITADEL or at Forgejo.

Disable the hosted Login UI so ZITADEL serves its built-in login, which needs
no machine user. Re-enable only after creating `login-client` and registering
the public key that matches zitadel-login-service-key.

Also register both callback spellings for the forgejo and paperless apps: the
callback path follows the login-source name, so a rename between authentik and
zitadel must not break sign-in.
