feat(frontend): Hide pending reviews panel while execution is RUNNING/QUEUED

Defense in depth: prevent users from seeing/clicking review panel before
execution pauses for review.

Before:
- Reviews panel could show while execution is RUNNING
- User could click to open panel and see pending reviews
- Confusing UX: why are reviews shown if graph hasn't paused yet?
- Could lead to frustration when backend rejects the approval attempt

After:
- Panel hidden if execution status is RUNNING or QUEUED
- Panel only shows when status is REVIEW (paused for review)
- Clear UX: reviews appear only when execution needs user input

Benefits:
1. **Better UX**: No confusion about when to approve reviews
2. **Prevents invalid attempts**: User can't try to approve while running
3. **Works with backend validation**: Frontend hides, backend rejects
4. **Clear state**: Panel visibility directly matches execution state

Changes:
- Added status check: hide if RUNNING or QUEUED
- Panel shows only when execution has paused (REVIEW/INCOMPLETE)
- Existing polling logic still works for real-time updates
