- New NavDrawer + hamburger menus for the app and admin layouts (below
md there was previously no navigation at all)
- Disable the dead Documents nav link that routed to the marketing
landing page via the catch-all route
- Replace the decorative topbar search with a debounced clients+cases
search dropdown (keyboard navigable, loading/error/empty states)
- Surface dashboard API failures: retry banner, em-dash KPIs, and a
retryable error state on the recent-cases card
