chore(ui): remove dead code from navigation redesign
Deleted:
- ScopeTrail component (replaced by inline breadcrumb in TopBar)
- ExchangeList component (replaced by Dashboard DataTable)
- ExchangeDetail page (replaced by inline split view)
Removed from Dashboard:
- flattenProcessors() function (unused after detail panel removal)
- 11 dead CSS classes (panelSection, overviewGrid, errorBlock,
inspectLink, openDetailLink, filterBar, etc.)
