UI polish: centering, search width, dropdown contrast, cover thumbnails, branding, sticky headers

- Constrain main content to max-w-5xl centered
- Widen search input (w-72 md:w-80 lg:w-96)
- Search dropdown: card with shadow, border, and primary-tinted hover
- Branding: SVG music note icon + gradient text + tagline
- Covers: 64px with front-250 thumbnail URL for faster loading
- Badge colors per type (primary/secondary/accent/ghost)
- Sticky table headers via table-pin-rows
- SVG icons for Add/Remove/RSS/OPML buttons
- Consistent hover transitions across tables
