Contact Icons Aligned
The About window now removes the contact placeholder and moves the five app icons into the Contact row.
# Contact Icons Aligned
This update tidies the About window by replacing the contact placeholder with real clickable social icon entries.
## Changes
- Removed the placeholder contact text.
- Moved the X, GitHub, Bilibili, Instagram, and Discord icons into the Contact row instead of keeping a separate icon strip below the intro copy.
- Switched the five platforms to local SVG brand icon assets while keeping the small XP-style icon buttons.
- Social links still read admin-configured URLs through the public read-only endpoint, open in a new tab, and keep `aria-label` text.
- Updated the public CSS / JS cache version, with icons wrapping inside the Contact row on narrow screens.
