fix(update-apps): dry-run uses check_for_gh_release args, not Source header

The # Source: header can point to a different repo than what
check_for_gh_release actually queries (e.g. RustDesk uses
lejianwen fork, not official rustdesk repo).

Now parse both app name and source repo directly from the
check_for_gh_release call in the ct script:
  check_for_gh_release "appname" "owner/repo"

Also fix $HOME/.appname path expansion in pct exec context.
