1. addEvent Parameter Update: Added satisfied duration to
addEvent, making duration testable in CSTest.
2. CSDefaultNetworkRematchMetricsTest Refactor: Tests now use
expectAddEvent with argThat and InOrder for more deterministic
verification.
3. New Unit Test: Added a test to demonstrate a metrics reporting
issue during per-app default network request updates.
Test: atest ConnectivityCoverageTests --test-filter 'DefaultNetworkRematch*' \
