TheFinAI/FinMR became gated; the build fetched it anonymously, so every rebuild died with 401 and took the submission portals down. HF_TOKEN is now mounted as a BuildKit secret, and an unavailable download degrades the practice phase to pending instead of failing the deployment.
FINREASON_DEADLINE_<PHASE> holds the instant the phase closes; unset means the phase stays open, so this change alters nothing until the variable is set.
