/**
 * Unified user menu - used by the topbar avatar AND the sidebar-footer
 * profile row. Encapsulates:
 *   - Profile / Settings / Notification preferences links
 *   - Dark-mode toggle
 *   - Sign out
 *   - Inline port switcher (when the user has access to >1 port)
 *
 * Everywhere a "click my profile" affordance lives, it should mount this
 * component. That keeps the menu items consistent regardless of which
 * trigger the user reached for.
