Fix concurrency key so ciflow tag re-pushes cancel prior runs

Tag-triggered workflows built their concurrency group from
`github.event.pull_request.number || github.sha`. On a `ciflow/*` tag
push there is no PR number, so the group keyed on `github.sha`; every
re-push of a tag pointed at a new sha, landed in its own group, and
never cancelled its predecessor. On Aug 5 a burst of ciflow re-pushes
fanned out to 46 shas / 117 runs and buried the shared macos-m1-stable
fleet, taking main macOS coverage to 0.

Adopt the expression already used by periodic.yml: fall back to
`github.ref_name` (stable across re-pushes of the same tag) and gate the
sha term on `github.ref_type == 'branch'` so branch pushes keep per-sha
isolation. periodic.yml is the reference; every other workflow now
converges on that same group expression. Also drops a stray double dash
in the nightly/test-backend group strings.

Applies to all workflows carrying the old key, including the seven that
are not tag-triggered, so the pattern is uniform and cannot be
copy-pasted back in.
