Add a redesigned hero section to the public playlist page displaying
community-generated totals for playlists and episodes, plus new string
translations (English, German, French). Eager-load user, limited episode
previews, and first gallery image to reduce N+1 queries. Cache aggregate
statistics for 10 minutes to improve performance on high-traffic pages.
Enhance the navigation with a modern floating glass design, new Browse and Community dropdown links, and improved theme/blur toggles that now handle multiple instances. Update dropdown components with rounded styling and support for wider widths, refine nav-link active states, and add navigation feature tests.
