Support multilingual Pink Panther ISOs

[astrovm]

Summary

• support every Pink Panther language release recognized by the bundled ScummVM Pink engine
• detect the release language from its ORB payload and mount the matching disc files
• support alternate Spanish releases and the compressed Polish Passport layout
• store each disc's actual ISO size and detected language instead of assuming English media sizes
• update ISO download progress, validation messaging, and regression coverage

Root cause

The launcher hard-coded the total ISO size and payload sizes of the two English discs. Valid localized releases use different ISO, executable, support-file, and ORB sizes, so they were rejected before ScummVM could start them.

Impact

Users can now select or download supported localized Pink Panther ISOs without a language selector. The launcher identifies the release automatically while preserving temporary and persistent browser-copy workflows.
