Trigger a dashboard run against the rotated sheet secrets

An empty commit, deliberately: the repository secrets were replaced on
2026-09-01 and nothing has exercised them, but workflow_dispatch is unavailable
until dashboard.yaml is on the default branch, so a push to this branch is the
only way to start a run before merge. A mistyped secret fails at collection with
"No Google Sheet ID", so one green run settles it.

The temporary push trigger is removed once that run is green — after which this
is the last thing that could have started one.
