feat(ui): mobile responsive layout

- App: hamburger menu on mobile, nav links hidden below md breakpoint
- LogSearch: collapsible sidebar on mobile, stacks above results vertically
- Incidents/Sources: overflow-x-auto on table containers, min-w to preserve
  column layout on desktop; drawer action buttons flex-wrap on small screens
- Bundles: flex-wrap on header row, hide source_host + timestamp below sm
- General: p-4 sm:p-6 padding on all standard views
