pptx704 c93ad5e2db fix: harden pause flow with connection isolation and UFFD event handling ...

Restructure pause to: block new operations (StatusPausing), drain proxy
connections with 5s grace, force-close remaining via context cancellation,
drop page cache, inflate balloon, then freeze vCPUs. Previously connections
could arrive during the pause window and API operations weren't blocked.

Handle UFFD_EVENT_REMOVE/UNMAP/REMAP/FORK gracefully instead of crashing
the UFFD server. These events fire during balloon deflation on snapshot
restore, killing the page fault handler and preventing VM boot.

Also adds ConnTracker.ForceClose() with cancellable context propagated
through the proxy handler, so lingering proxy connections are actively
terminated rather than left dangling.
