f1-stream: consume Forgejo-registry image; drop in-monorepo source

The actively-developed f1-stream (infra files/ copy: 12 active extractors +
Playwright/chrome-service verifier) is now its own repo viktor/f1-stream and is
the deployed app (replacing the stale March github build).

- main.tf: image -> forgejo.viktorbarzin.me/viktor/f1-stream:${var.image_tag}
  + image_pull_secrets registry-credentials. Image stays in KEEL_IGNORE_IMAGE.
- Remove stacks/f1-stream/files/ (source now in viktor/f1-stream).
- docs/plans: extraction design + plan pair.

Applied via tg + kubectl set image to forgejo:24857a82; live /health green.
