fix(ci): nothing a CI job starts outlives it, even when the runner kills the job
A migration-smoke stack (PostgreSQL and SeaweedFS) ran on the shared
runner for two days. Every CI script removes its stack in an EXIT trap,
but a trap never runs when the runner kills the job container: a
cancelled job, or the runner's own time limit (Gitea 1.24 ignores
timeout-minutes). Reproduced: SIGKILL of the infrastructure smoke
mid-run leaves exactly that stack running.

Cleanup now has three layers:
- the script's own trap, unchanged;
- a final `if: always()` step in every job that starts stacks
  (infrastructure-smoke, migration-smoke, image-build, deploy-smoke)
  runs `scripts/ci-sweep.sh --job`, which removes everything that job
  started at any age;
- a first step in each of those jobs runs `scripts/ci-sweep.sh --stale`,
  which removes CI stacks older than three hours: what a killed job left
  before it could clean up.

How stacks are found is defined once, in scripts/lib/ci-project.sh:
- every CI Compose project is named `ekklesia-ci-<run>-<attempt>-<job
  key>-<kind>-<unique>`, and Compose labels its containers, networks and
  volumes with that name;
- the deploy smoke labels everything it starts outside Compose:
  browser, kiosk and driver containers, the kiosk volume, built images;
- images also record when CI built them. An image's own creation time
  can be its base's (BuildKit, metadata-only builds), and the sweep
  removed a brand-new image as "old" until it stopped trusting that.

The job key is per matrix leg, so one topology's cleanup cannot remove
the other's running stack. The sweep never touches anything outside the
ekklesia-ci- prefix, disconnects rather than removes a job container
attached to a stack's network, and refuses --job outside CI. Network
creation times are read as RFC 3339; Docker's default form was
unparseable.

scripts/test-ci-sweep.sh proves all of that against real Docker, and
CI runs it before relying on it. security.md and testing.md document
the rule, and that it complements, not replaces, a runner-side reaper.
