Rewrite help panel to use the same grouped navigation pattern as the admin aside panel (details/summary with nav links). Remove inline keyboard shortcuts table and about section. Panel now shows permission-gated navigation groups: Documentation (docs viewer, API docs) and System (system info). Remove custom CSS — panel inherits existing app-sidebar-admin-nav styling.
