GS_PH_VERSION command, per-printhead demo UI with --printheads CLI arg

Add getPhVersion(printheadId) to Xpl2Client with phVersionReceived signal
carrying all 8 response fields. Mock server echoes canned version data for
any requested printhead ID.

Demo app accepts --printheads N (default 10) to simulate N printheads.
The UI shows a scrollable per-PH list with individual and bulk version
query buttons, updating each row's version info on response.
