feat(ui): Task pool toggle, sortable columns, worker slot visualization

Tasks Dashboard:
- Add clickable Pool Open/Paused toggle button in header
- Add sortable columns (ID, Role, Store, Status, Worker, Duration, Created)
- Show menu_type and pool badges under Store column
- Add Pool column to Schedules table
- Filter stores by platform in Create Task modal

Workers Dashboard:
- Redesign pod visualization to show 3 worker slots per pod
- Each slot shows preflight checklist (Overload? Terminating? Pool Query?)
- Once qualified, shows City/State, Proxy IP, Antidetect status
- Hover shows full fingerprint data (browser, platform, bot detection)

Backend:
- Add menu_type to listTasks query
- Add pool_id/pool_name to schedules query with task_pools JOIN
- Migration 114: Add pool_id column to task_schedules table
