fix: finalize emergency automation fix with validation

- Restore automation-service-simple.ts from backup
- Container builds successfully with emergency routes active
- Add comprehensive validation test (test-emergency-fix.js)
- Confirmed: rate limiting works, 5-minute cooldown enforced
- Confirmed: Chromium processes stay at 0 after operations
- Confirmed: start/stop cycle works properly
- Emergency system protects against runaway automation loops

VALIDATION RESULTS:
 Emergency rate limiting: WORKING
 Process cleanup: WORKING
 Start/stop cycle: WORKING
 Status reporting: WORKING

Issue RESOLVED: No more multiple TPs/SLs execution loops
