presets). Header dropdown now has a Settings link + Logout button only.

Replace static logout button with a dropdown triggered by clicking the
username badge. Dropdown shows accent color presets and a logout button.

Replace all hardcoded #c8ff00 / rgba(200,255,0,...) with CSS custom
properties (--accent, --accent-rgb) so the accent color updates live.
Add themeStore (Zustand + localStorage) with 6 presets (Лайм, Синий,
Розовый, Фиолет, Оранж, Минт). Add ThemeApplier component that syncs
CSS vars on load. Add color picker UI section in ExtraTab.
