zona-exclusion: stage Infisical-backed SMTP secret with key remap (3a)

InfisicalStaticSecret syncs shared /smtp-gmail -> zona-exclusion-secrets-infisical,
template-remapping UPPER_SNAKE -> hyphenated lowercase smtp-user/smtp-pass to match
the deployment secretKeyRef. Old secret stays live until 3c.
