[nexus] add test 5.6.6 Network data expiration (#12506)

Browse Source 
This commit adds a new Nexus test case for 'Network data expiration'
(5.6.6) as specified in the test specification.

The test verifies that network data is properly updated when deleting
a prefix or removing a server from the network.

Summary of changes:
- Implemented Nexus test 5.6.6:
    - Added tests/nexus/test_5_6_6.cpp: Implements the test execution
      including topology formation, on-mesh prefix configuration, and
      silent power-off of a border router. The test uses direct method
      calls, sets log level to note, and uses AllowList for
      connectivity.
    - Added tests/nexus/verify_5_6_6.py: PCAP verification script.
      Validates CoAP Server Data notifications, MLE Data Responses,
      and Child Update exchanges, ensuring correct network data
      propagation and expiration.
- Updated build and execution scripts:
    - Modified tests/nexus/CMakeLists.txt to build the new test.
    - Updated tests/nexus/run_nexus_tests.sh to include 5_6_6 in the
      default test list.
