ci: the integration lane finds its own Postgres, not another job's

Run 8653 failed at 'alembic upgrade head' with a password error: two
integration jobs were on the runner at once, and the name=integration
filter took the other one's database (#5312). The lookup is now scoped to
this job's GITEA-ACTIONS-TASK-<id>- prefix, read from the job container's
own name, and requires exactly one match.
