ENG-2335 Add a shared check for whether an imported node is published to a group

[maparent]

Reviewer brief

• Result: getPublishedGroupIdsByRid returns, for each imported node RID, the user's groups that can read that node: groups with reader or editor access to its space, plus groups with partial access and a ResourceAccess grant for the node.
• Review focus: the space-level read uses the my_pseudo_accounts view, not SpaceAccess, because the SpaceAccess select policy hides partial rows. See the ticket comment.
• Risk or follow-up: the ResourceAccess batch size is set from the group count so that a batch stays under max_rows (1000). Rows from local ids that collide across a batch's spaces are not counted, and the hosted max_rows is assumed to match supabase/config.toml. Paging with getAllPages would remove both assumptions; I decided that it was adding scope, but it's certainly a reasonable thing to do.

Verification
