feat: add GoAlert Cloudron package (Monitoring) [#633]

Official-image wrapper of goalert/goalert 0.34.1 (digest-pinned),
single Go binary + postgresql only. Native generic OIDC wired from
the platform provider (GOALERT_OIDC_*), data-encryption key
persisted, optional first-admin basic auth. grind-stack verified:
full migration chain, serving, origin canonicalization correct.
18th package; category table reconciled to the 46-app set.
