ci(oxfmt): trigger ecosystem ci via label (#22905)

The Oxfmt ecosystem CI trigger was still using `/oxfmt-ecosys` comment
command, while the newer monitor-oxc flow uses a short-lived PR label to
kick off the external workflow and then removes the label afterward.

This moves Oxfmt to the same pattern. Adding `run-oxfmt-ecosystem-ci` to
a PR now creates or updates the tracking comment, dispatches
`oxfmt-ci.yml` in `oxc-ecosystem-ci` with the PR ref, and removes the
trigger label after dispatch. The app release workflow now adds that
label to release PRs instead of directly creating the Oxfmt comment and
dispatching the external workflow itself.

Oxlint's release ecosystem dispatch is left as-is for now, since this
change is scoped to the Oxfmt workflow requested in the PR follow-up.
