Harden OPNsense build wait detection

Improves VM install completion detection by encapsulating screendump hashing in a helper, clearing stale dump files, and trying both `qm monitor` and `pvesh` monitor paths. The stability check now tolerates alternating A/B frames from a blinking login cursor instead of requiring one identical frame. It also adds elapsed-time progress output and a safe fallback to a fixed 12-minute wait when screendumps are unavailable, avoiding false completion or endless polling.
