Clear screen and force Static component remount when approval state is
cleared. This fixes "streaking" where fragments of approval dialogs
would appear mixed with transcript content.
The issue was caused by Ink's line count tracking getting confused when
large UI components (approval dialogs, plan preview) disappear abruptly.
Applied fix in:
- sendAllResults (normal approval flow)
- sendAllResults early return (cancelled flow)
- handleInterrupt (Ctrl+C during approvals)
- handleCancelApprovals (cancel all approvals)
