The previous endpoint blocked recreation if the tunnel was 'healthy'
or returned an 'error_response', making the Recreate Tunnel button
ineffective in many cases.
- apps/api/src/api/tool_instances.py: removed the health-check guards
from recreate_tunnel_endpoint. It now unconditionally stops the old
tunnel and creates a new one, then commits the new URL to the DB.
- Frontend useInstanceActions already calls onRefresh() after success,
so the UI updates with the new tunnel URL automatically.
