fix: regenerate OpenAPI types, fix search scoping by applicationId

The identity rename (application→applicationId) broke search filtering
because the stale schema.d.ts still had 'application' as the field name.
The backend silently ignored the unknown field, returning unfiltered results.

- Regenerate openapi.json and schema.d.ts from live backend
- Fix Dashboard: application→applicationId in search request
- Fix RouteDetail: application→applicationId in search request (2 places)
- LayoutShell: scope command palette search by appId/routeId
- LayoutShell: pass sidebarReveal state on sidebar click navigation

Note for DS team: the Sidebar selectedPath logic (line 5451 in dist)
has a hardcoded pathname.startsWith("/exchanges/") guard. This should
be broadened to simply `S ? S : $.pathname` so sidebarReveal works on
all tabs (dashboard, runtime), not just exchanges.
