feat(ci): add Print runner wait time step to all workflow jobs

Adds a first step to every CI job that measures how long the job sat in
the queue before a runner picked it up. Uses the Forgejo tasks API with
github.token (no new secrets required) and prints unknown if the API
lookup fails, so the step never blocks the job.

Closes #504
