[nexus] add SRPC-TC-1 for SRP client re-registration (#12779)
This commit adds the Nexus test case 1_3_SRPC_TC_1 which verifies that the SRP client correctly handles re-registration with active SRP servers, especially when multiple Border Routers are present, as per the Thread 1.3 test specification. The implementation includes: - tests/nexus/test_1_3_SRPC_TC_1.cpp: Executes the test sequence by configuring two Border Routers (BR_1 and BR_2), a Router, and an End Device (ED_1 as DUT). It simulates BR_1 (the initial SRP server) becoming unresponsive and verifies that the DUT correctly switches to BR_2. It also verifies that the DUT stays with its current server (BR_2) even when a numerically lower server (BR_1) is re-enabled. - tests/nexus/verify_1_3_SRPC_TC_1.py: Performs automated verification of the captured traffic (PCAP). It checks for correct SRP Update packets to the expected SRP servers and validates that the DUT behavior matches the specification criteria. - Integrated the new test into tests/nexus/CMakeLists.txt and tests/nexus/run_nexus_tests.sh. The test ensures robust SRP client behavior in dynamic networks with multiple SRP servers.

# 3.1. [1.3] [CERT] [COMPONENT] Re-register service with active SRP server - Multiple BRs - No AIL
|

#
|

# 3.1.1. Purpose
|
||||
# To test the following:
|
||||
# - DNS/SRP Unicast Dataset(s) offered in the Thread network
|
||||
# - Detects unresponsiveness of the SRP server and sends SRP update to another active SRP server
|
||||
# - Detects a second, numerically lower, SRP server and DUT stays with its current SRP server and does not switch
|
||||
# to the numerically lowest SRP server
|
||||
# - Registered service is automatically re-registered with active SRP server before timeout
|
||||
# - In the absence of an OMR prefix, mesh-local (ML-EID) address will be used by SRP client.
