chore(deps): update golang:1.27.3 docker digest to 9d5ff8e (#208)

Part of the dancefinder.unbound.se cutover to Frostmoln Production (infra: unboundsoftware/infra#1896, already applied).

- Replaces the AWS `deploy-prod` job (failing since CI left AWS) with `deploy-prod-frostmoln` (`deploy prod-frostmoln -n dancefinder`), as schemas did.
- Restricted securityContext (runAsNonRoot, drop ALL, seccomp RuntimeDefault) and `imagePullSecrets: oci-registry` (Platform registry).
- Runs as uid 65534. The Frostmoln CronJob is suspended by hand after its first deploy and resumed by `migrate-db.sh dancefinder --cutover` (not in the manifest, so later deploys don't re-suspend it).

Merging deploys to Frostmoln only; DNS still points at AWS until the cutover.
