switch: fix the unquoted python string that broke status with no --name

`cmd_status` has two paths. The `--name` path filters on an exact tag and
works. The no-name path — the "show me every switch on this box" survey,
which is how an orphan switch under a different name would be found —
built its python with shell quote-juggling and never closed the string
literal, so it died with a SyntaxError every time.

It failed loudly (rc=1, a traceback) rather than reporting "no rules", so
it never lied about the state. But it also meant the survey path had
never once run, which is the more useful lesson: every branch of a safety
tool needs exercising, not just the branch the happy path takes.
