perf(chat): stop the resource picker fetching schedules it no longer shows

Dropping the `scheduledtask` group from the add-resource dropdown left
`useWorkspaceSchedules` behind, so the picker still issued a workspace
schedules request whose result never reached a group.

Worse than a wasted request: `schedulesPending` was still in the hydration
gate, so the whole picker waited on that response before it could settle, and
`schedules` was still a `useMemo` dependency, re-running the group build when
it resolved.

The hook and its route stay — `/api/schedules?workspaceId=` still correctly
lists workflow schedules, unlike `createScheduleContract`, whose route this
branch removed.
