Fix SSH connectivity in lab tool using admin aliases

- Updated lab status command to use admin SSH aliases (admin-sleeper, admin-grey, admin-reverse)
- Fixed SSH authentication issues by using correct admin keys
- Improved verbose mode to show detailed connection attempts
- Updated legacy deployment to use admin aliases for consistency
- Now properly connects to sleeper-service and grey-area via admin access
- reverse-proxy showing as unreachable due to fail2ban (expected security behavior)

Resolves SSH connectivity issues that were blocking task completion assessment.
