feat(health-monitoring): complete instance health monitoring implementation

Backend:
- Container startup verification with docker inspect polling
- Readiness probe integration with ToolType configuration
- Enhanced health endpoint checking container + tunnel status
- Smart tunnel recovery distinguishing connection errors vs HTTP errors
- New status states: starting, probing, unhealthy

Frontend:
- Updated status badges for new states (starting, probing, unhealthy)
- Show tunnel error only when tunnel_status is unreachable
- Show app error badge with status code for error_response
- Add collapsible probe output section for diagnostics
- Only show Recreate Tunnel button for unreachable tunnels

Quality Gates:
- Frontend type checking: PASSED
- Frontend build: PASSED
- Backend unit tests: 56 passed
