useCostInsights before constructing the query key and request fan-out, using the
unique collections for sorted values, enabled checks, single-component handling,
and downstream request generation. Preserve existing behavior for non-duplicate
inputs, and add a regression test covering duplicate envs to ensure requests and
totals are not duplicated.

- Around line 24-93: Update the query callback that builds the title map in
useDimensionTitles to track title conflicts separately in both the
project-component and namespace/environment fetch paths. When the same
entity.metadata.name receives different non-empty titles, mark that key
ambiguous and remove it from the returned map so CostInsightsTable falls back to
the raw dimension name; preserve unique title mappings.

Do we really need this Header component ? Its being used only in CostInsightsPage now , but do we really need a separate header for CostInsights Page ? Can't we use the same header that's used in Catalog, Platform Overview pages ?
