Pull request overview

Adds/adjusts print-specific styling for the Teacher Tool’s code evaluation results view to improve printed output across browsers (Chrome/Firefox/Safari), addressing pxt-arcade issue #7439.

Changes:

• Update global print CSS to avoid html/body sizing/overflow constraints and apply WebKit-friendly body sizing.
• Add @media print overrides in EvalResultDisplay styles to remove scroll/height constraints and improve pagination/print contrast.
• Add print pagination tweaks in CriteriaInstanceDisplay to reduce awkward page breaks.

page-break-inside/page-break-after are legacy print properties. To improve standards compliance and compatibility, consider using the modern equivalents as well (e.g., break-inside: avoid and break-after: avoid/avoid-page) alongside these rules throughout this module.

page-break-inside is a legacy print property. Consider adding the modern equivalent (break-inside: avoid, optionally alongside page-break-inside) to improve standards compliance and print behavior across browsers.
