Subject: [PATCH] feat(ci): add test_run workflow input for -test.run filter

Pass an optional regex through to each suite's '\''go test -test.run'\'' so
dispatches can target a single test (e.g. '\''^TestMultinodeIPSec$'\'') without
running the full multinode suite. Threaded through single, multinode, and
reboot suite invocations; empty input preserves current behaviour.
