- Set muted sidebar text equal to the readable sidebar text so inactive
nav items and section labels are never dimmed
- Active item remains distinguished by its accent background and border
- Derive sidebar text color from the main admin text against the actual
sidebar background (not canvas/surface), guaranteeing contrast
- Brighten muted sidebar text to 82% of the readable text color so
inactive nav items and section labels stay clearly visible
- Add 6 new admin color DB keys (admin_canvas, admin_surface, admin_text,
admin_text_muted, admin_border, admin_sidebar_bg) that override the
derived admin palette
- Extract adminPaletteCss() from themePaletteCss() for reuse
- Generate admin CSS variables in both :root and html.dark with overrides
- Persist admin color settings via saveTheme action
- Add Admin panel (HK) section to /admin/theme with color pickers
