v0.54.2

Changed

• Liquid Glass – Settings module: Migrated settings.css and settings-nav.css to Glass design tokens. Settings cards (.settings-card), CalDAV account items, module rows, and the settings sidebar now use --glass-bg-card, --glass-bg-elevated, --radius-glass-card/--radius-glass-inner, --glass-border-subtle, and --glass-shadow-* tokens. Interactive rows (.toggle-row, .cat-row, .caldav-calendar-item) use --glass-bg-card-hover on hover. Tooltips use --glass-shadow-lg. Sidebar navigation items use --radius-glass-inner with glass hover states.
