chore(codeowners): retarget the dashboard entries at their new paths

The V1 dashboard retirement moves, merges and renames most of the paths
this section names. Doing that inside the stack meant six PRs each carried
a slice of the same edit and each needed the CODEOWNERS owner's review;
collecting them here makes it one review of the whole delta.

Net effect: same team owns the same code, addressed by where it now lives.

- api/types/dashboard -> types/api/dashboard, plus the new types/api/widgets
- ListOfDashboard, NewWidget, DashboardWidget, DashboardContainer,
  GridCardLayout, PublicDashboardContainer are gone; what survives of them
  lives under container/WidgetCard
- the shared chart layer moved to lib/visualization
- DashboardPageV2 / DashboardsListPageV2 dropped their suffix

Merge this after the stack lands, so no path is left unowned in between.
