Code Merge Request #1: Add Polish localization (merged)

Hi Maarten,

I have completed the Polish localization based on the develop branch.

The change includes:

• Polish translations of the application interface, menus and preferences
• Polish recorder, eraser and disc information dialogs
• Polish inspector and data options
• Polish help pages and application metadata
• Polish resources registered in the Xcode project
• Consistent terminology for optical drive, discs, recording and filesystems

I validated all Polish .strings files, preserved format placeholders, and tested the project build with the current Xcode.

Please review and merge if everything looks correct.

Best regards,
Łukasz
