feat: allow groups to specify which cids to show member posts from (#8875)

* feat: allow groups to specify which cids to show member posts from

* docs: fix tests for openapi

* fix: test breakage caused by improper conditional

* feat: server-side checking of memberPostCids for validity

* feat: admin panel template update to select categories to include

* refactor: privilege helpers.isUserAllowedTo

... to helpers.isAllowedTo, allowing group names to be passed in
