feat(remote): add desktop SSH remote instances lifecycle and UX (#515)

* feat(remote): add desktop SSH remote instances lifecycle and settings UX

* fix(remote): cancel SSH modal connect and correct desktop runtime detection

* fix(remote): unblock ssh auth flow and disconnect on instance removal

* fix(remote-ssh): harden remote lifecycle, auth probing, and port forwarding reliability

Improve SSH remote stability by correctly handling authenticated external probes, accepting ControlMaster handoff behavior, making reconnect detection tunnel-aware, and applying extra forwards through the shared master connection with local listener validation.
