Description
This PR splits
getByIds
into two methods: one that doesn't include any relations by default and one that includes all of them. Of its current usages, all of the ones internal to the server have been checked to see which, if any, relations are required (most of them don't require any). The ones used for API responses use the variant with all relations since they're more work to figure out.Also, as suggested in #7909, this adds a few indices needed for queries involving the stack, tag and person relations to be performant. I tested and can confirm the massive performance difference described in that issue.
Fixes #7909
