fix(ci): replace --logger with TUnit-compatible test arguments

[Copilot]

After TUnit migration, CI workflows failed with "Unknown option '--logger'" because the test runner scripts were still using VSTest/xUnit arguments incompatible with Microsoft.Testing.Platform.

Changes:

• Updated .github/actions/run-dotnet-tests/run-unix.sh to use --report-trx and --report-trx-filename
• Updated .github/actions/run-dotnet-tests/run-win.ps1 with matching TUnit arguments
• Removed legacy --logger "trx;LogFileName=..." syntax

Before:

dotnet test --project "$PROJECT_PATH" -c "$CONFIGURATION" -f "$tfm" --no-build \
         --logger "trx;LogFileName=testResults-$tfm.trx" \
         --results-directory "$RESULTS_DIR"

After:

dotnet test --project "$PROJECT_PATH" -c "$CONFIGURATION" -f "$tfm" --no-build \
         --report-trx --report-trx-filename "testResults-$tfm.trx" \
         --results-directory "$RESULTS_DIR"
