fix: usr: Fix allow-recursion/allow-query-cache inheritance

The merging of the user options and defaults into the effective configuration broke the mutual inheritance of the `allow-recursion`, `allow-query`, and `allow-query-cache` ACLs, and of the `allow-recursion-on` and `allow-query-cache-on` ACLs. This has been fixed.

Closes #5647

Merge branch '5647-allow-recursion-inheritance' into 'main'
