fix(admin): show nav items in mobile sidebar drawer

[all3f0r1]

What does this PR do?

Fixes the mobile sidebar not displaying navigation pages within sections (Content, Manage, Admin, Plugins). The section headers were visible but all pages inside them were hidden.

Root cause: Kumo's Sidebar component renders the mobile sidebar inside a Sheet/Dialog. The inner div[data-sidebar="sidebar"] gets data-mobile="true" but no data-state attribute. Kumo's SidebarGroupContent uses grid-rows-[0fr] as default (hidden) and only shows content via group-data-[state=expanded]/sidebar:grid-rows-[1fr]. Without data-state="expanded" on mobile, the selector never matches and all collapsible group content stays invisible.

Fix: Adds a CSS override targeting .emdash-sidebar[data-mobile="true"] [data-sidebar="group-content"] to force grid-template-rows: 1fr in the mobile drawer.

Closes #454

Screenshots / test output

This is a CSS-only fix targeting the mobile sidebar drawer. The change is a single grid-template-rows: 1fr !important override scoped to [data-mobile="true"], matching the existing pattern used for collapsed sidebar icon mode.
