Redesign player Stats for readability and less visual overload

[jlipworth]

Problem

The player Stats page is too much right now: dense information, awkward line wrapping, and not enough hierarchy to make it easy to scan.

Desired direction

• Put the useful at-a-glance playback information first.
• Group related metrics with clearer labels, spacing, and consistent value alignment.
• Keep detailed diagnostics available, but consider putting them behind expandable sections rather than showing everything at once.
• Handle long values and narrow layouts deliberately instead of wrapping labels and values into a hard-to-read wall of text.
• Preserve metric accuracy and accessibility; do not solve density by simply shrinking the text.

Acceptance

• Review the current Stats surfaces and propose a simpler information hierarchy.
• Verify readability with long values, compact layouts, and larger text sizes on affected platforms.
• Keep important playback facts easy to find and advanced diagnostics accessible.
• Avoid changing playback behavior or metric semantics as part of the redesign.

Priority

Low-priority polish / backlog. Not a release-candidate or App Store submission blocker. This issue records the request only; no implementation is requested now.
