The GUI assumed the 5.1 fallback unconditionally, so guests created with a newer QEMU were shown a version they are not running. Derive the version from the QEMU version recorded at creation time instead, in both the hardware view and the machine edit dialog, and mark it as implicit so it stays distinguishable from an explicit pin. The edit dialog also pre-filled the version field with the fallback, which both suggested a version the guest might not be running and caused any other change in the dialog to submit that stale value. Leave the selector at 'latest' instead, so a version can be picked deliberately, and show the effective version as a read-only field together with a hint recommending an explicit pin. The advanced section is expanded so the hint is visible without further interaction.
