fix(sops-cmp): correct loki s3 path (.loki.storage.s3), emit authentik-secrets separately, drop broken discover — merge via server/worker/migrate envFrom

Loki keys are under .loki.storage.s3 not .loki.s3 (returned null). Emit a separate
authentik-secrets Secret (not 'authentik', which the Helm chart owns) and merge it
via envFrom on server/worker/migrate. Remove discover fileName (caused MatchRepository
timeouts; app names the plugin explicitly).
