Redesign sidebar theme controls layout and fix dark mode visibilityclaude/add-css-themes-QGTmP

Split light/dark into ☀ ☽ buttons above a horizontal rule, with
the 5 style emoji below. Increases icon size from 0.8rem to 1rem.

Replaces opacity-only approach with explicit rgba(0,0,0) color in dark
mode (sidebar remains grey in dark theme, so icons need dark ink).
Switches hover/active backgrounds to neutral rgba(128,128,128) so
they work correctly across all themes and modes.
