[nexus] add SRP-TC-4 for SRP key lease handling (#12760)
This commit adds a new Nexus test case 1_3_SRP_TC_4 which implements the test specification for SRP key lease handling. The test verifies that: - A service instance name cannot be claimed even after the service instance lease has expired, as long as its key lease remains active. - The SRP server correctly manages key leases and rejects registration updates for hosts or services that are still claimed by a previous registration during the key lease period. - DNS and mDNS responses correctly reflect the state of registrations and their expirations. Changes: - Add tests/nexus/test_1_3_SRP_TC_4.cpp for test execution. - Add tests/nexus/verify_1_3_SRP_TC_4.py for pcap verification. - Update tests/nexus/CMakeLists.txt to include the new test. - Update tests/nexus/run_nexus_tests.sh to add it to DEFAULT_TESTS.
