feat(ui): redesign public reading and complete glass workspace

Add scoped public navigation, reading progress, focus and print controls without loading the editor. Polish responsive settings, graph and media layouts.

Correct share expiry units, preserve math and code during link maintenance, and normalize Markdown destinations for templates and note navigation. Verify browser flows and document the new tools.
