- Reorganize sidenav into collapsible groups (Tenancy, Data,
Integrations, Communications, Observability, AI & Search) with
Overview/Settings pinned at top/bottom. Group open/close persists in
localStorage; the group containing the active route auto-opens.
Icon-only collapsed rail flattens to a single icon column. Sub-items
inside groups drop their per-item icons and indent under the header.
- Fix mobile sheet scroll — the nav couldn't reach items past viewport
height. SheetContent is now flex-col h-svh, header shrink-0, nav
flex-1 min-h-0 overflow-y-auto.
- Settings page mobile fixes: section nav wraps instead of horizontal
scroll, top padding clears the floating actions pill, LLM config
card header and rows stack on narrow widths.
