POST /api/v1/jobs/{id}/budget-extension

Operation: extendJobBudget.

Append funded budget amendment (renter owner)

Idempotent. Appends one immutable amendment plus hold atomically; keeps original rate and snapshotted host-availability ceiling; bumps budget_version. Rejects once STOPPING begins. D-16 — budget_version changes only with a committed funding amendment.
