The multicam node-graph switch regression fails on Windows CI (the second
render still serves the first source: the selector does not reach the
evaluation) and multicam is not v0.5 scope. Mark the test ignored with
that reason so Windows CI can go green, and drop the temporary
media/graph probes added while diagnosing it (their findings live in the
git history) so un-ignoring it later starts from the original test.
