style(ui): nest picker list-header ::after override

Astro-Han · Astro-Han · commit 86dee217c339 · 2026-05-25T03:26:55.000+08:00
Address Gemini review feedback: nest the ::after { display: none } under
the header rule instead of repeating the four-deep selector chain. Same
compiled CSS, less duplication, matches list.css's nesting style.
