[nexus] add test 5.6.2 Network data propagation – Router as BR (#12485)

Browse Source 
This commit adds a new Nexus test case 5.6.2 which verifies that
the DUT, as Leader, collects network data information (stable/
non-stable) from the network and propagates it properly during
the attach procedure.

The test setup uses Router_1 configured as a Border Router with
both stable (2001::/64) and non-stable (2002::/64) prefixes. It
verifies that SED_1 (requesting stable data) and MED_1 (requesting
complete data) receive the correct subset of network data during
the attach procedure to the Leader (DUT).

Summary of changes:
- Created tests/nexus/test_5_6_2.cpp:
    - Implements test logic using direct C++ method calls.
    - Configures AllowList for Leader-Router1, Leader-MED1, and
      Leader-SED1 links.
    - Includes 1-line log outputs for each test step.
    - Adheres to requested block comment formatting.
- Created tests/nexus/verify_5_6_2.py:
    - Implements pcap-based verification of PASS criteria.
    - Validates selective prefix propagation based on child mode.
    - Verifies MLE Child ID and Child Update exchanges.
    - Follows requested Python filter formatting style.
- Updated tests/nexus/CMakeLists.txt to build the new test.
- Updated tests/nexus/run_nexus_tests.sh to add 5_6_2 to the
  default test list.
