Added `Core::AllowLinkBetween()` and `Core::UnallowLinkBetween()` helper methods to the Nexus test platform. These methods simplify establishing bidirectional links between nodes in simulation tests by handling the reciprocal `AllowList()` calls in a single step. Updated various Nexus test cases to utilize these new helpers, replacing manual bidirectional `AllowList()` calls. This change reduces verbosity and ensures consistency in how links are established in the test topology.
