runners: add github-runner-pimanager Deployment

FlowerCore.PiManager build run 26417714843 sat queued 5h with zero
self-hosted runners registered to the repo. PiManager was missed in
the Sprint 32 long-tail sweep — every other FC repo got a dedicated
repo-scoped Deployment with its own ACCESS_TOKEN registration, but
PiManager fell through the cracks.

Adds a 2-replica ephemeral runner Deployment matching the Signage /
DMS / Print.Web pattern (per-pod emptyDir caches, no shared PVC,
labels `self-hosted,linux,fc-build-linux`, shared github-runner-token
PAT). Once ArgoCD syncs, the queued job will pick up automatically.

 # runner must use per-pod emptyDir caches, not a shared ReadWriteOnce PVC.
