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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01H6eVuR4Yt3m7TbDTDwyZJi Reviewed-on: https://gitea.unbound.se/dancefinder/dancefetcher/pulls/203
