Deploy workforce/dev dataplane (Layer 2), mirroring the other domains

Real Konnect Control Plane 1dbd741c-0da2-4718-8c72-6f479530b371, PAT
in Vault. Replaces the TODO stubs with the proven three-file
pattern. JWT_AUDIENCE_WHITELIST includes mcp-workforce from the
start since Layer 3 was built the same session — see STATUS.md
section 23.

 # dataplane-workforce
 
 Layer 2 (Gateway infrastructure) for the **workforce** bounded context
-(domain team: workforce). `DataPlane`, `KonnectExtension`, certs (cert-manager),
+(domain team: workforce) — one Control Plane per environment, referenced

+`dataplane-customers`/`dataplane-payments`/`dataplane-sales` — see

+**IdP**: `https://keycloak.sttlab.local/realms/classic-models` (local
+in-cluster Keycloak), platform-wide default — see `../STATUS.md` sections
+15/16. `JWT_AUDIENCE_WHITELIST` set to `["workforce-api", "mcp-workforce"]`
+from the start — Layer 3 (REST + MCP) was built the same session, see
+`../STATUS.md` section 23.
+
+**Only `dev/` is real.** `staging/api-gateway/` and `prod/api-gateway/`
+still hold the original TODO placeholder files, not converted, not
+deployed.
+
+**Layer 3 is real here too**: `../workforce-api` (REST + MCP over `Office`
+and `Employee`) was built and deployed the same session — `Gateway
+workforce-dev`: `Programmed: True`, DNS entry added to `coredns-custom`
+(`workforce-dev.sttlab.local` → the `dataplane-ingress-workforce-dev-*`
+Service `ClusterIP`, same manual per-domain step documented in
+`../STATUS.md` section 17), all routes smoke-tested (`401`, not
+`404`/`502`).
+
+Self-service pipeline (`../konnect-platform` generating this content
+automatically) does not exist yet — still a stub per `../STATUS.md`.
+Everything here is hand-maintained.
