fix(hitl): isolate cancelPausedExecution failure from successful cancellation

Wrap cancelPausedExecution in try/catch so a DB error does not mask
a prior successful Redis or in-process cancellation. Also move the
resource-collapse side effect in home.tsx to a useEffect to avoid the
stale closure on the resources array.
