Release v1.1.2: publish container image + add security workflows

- Bump VERSION to 1.1.2 (no app behavior change from 1.1.1).
- release.yml: add workflow_dispatch so images can be published manually from
  the Actions tab in addition to on version tags.
- Add CodeQL code scanning (Python + JavaScript), free for public repos.
- Add Dependabot config for GitHub Actions and pip updates.

This is the first release to publish a multi-arch image to GHCR
(ghcr.io/allennpit/ads-bit).
