feat: Linear-style UI redesign with improved mobile experience
Major changes: - Redesign cabinet with Linear-style components and top navigation - Replace detail modals with dedicated pages (users, broadcasts, email templates) - Add email channel support for broadcasts - Remove pull-to-refresh, improve drag-and-drop on touch devices - Fix Telegram Mini App: fullscreen, back button, scroll restoration - Unify admin pages color scheme to design system - Mobile-first improvements: horizontal tabs for settings, better touch targets
