feat(test-suite): add per-service override support to fhevm-cli

[PanGan21]

Summary

• Extend --override to accept per-service filtering (--override coprocessor:host-listener,tfhe-worker), building only specified services locally while pulling the rest from the registry at their resolved tags
• Services sharing a Docker image are automatically co-selected (e.g., host-listener includes host-listener-poller)
• Invalid service names in overrides produce errors with the list of valid suffixes
• Non-overridden services in the same group now get compatibility args applied individually instead of all-or-nothing
• Warns user when trying to override services that share the same database
