# Details
When requesting CVE chart data, we were making a call to get the set of
tracked CVEs to filter the data by. Currently we're only _collecting_
data for the tracked CVEs, so there's no reason to make this call at
all.
When we add more filtering options and start collecting more data, we'll
need a call like this again, and will likely need to start caching the
results. Otherwise it's a multi-second cost per query on large
deployments.

## Testing
- [X] Added/updated automated tests
- removed some outdated tests
- replaced with a test that checks that when an entity filter returns no
items (an empty, rather than nil slice) we get empty buckets returned
rather than getting data for all entities. This is a regression test for
when we add filtering back.
- [X] QA'd all new/changed functionality manually
- validated that chart still loads and shows the same data.
- tried it on a load test env and saw dramatic API request time
improvement

## Summary by CodeRabbit
## Release Notes
* **Bug Fixes**
* Optimized CVE chart data retrieval by eliminating redundant queries,
reducing unnecessary database operations and improving performance.
* Fixed entity ID filtering logic to correctly handle edge cases and
prevent unintended filter interactions across metrics.
* **Tests**
* Added test coverage for chart data queries with empty entity filters.
* Improved test isolation to ensure metric-specific filtering behavior
is properly separated.
