fix(agent): Unbreak docker builds after repo restructure (#7164)

- Move `autogpt/Dockerfile` to `Dockerfile.autogpt`
  - Write new selective `.dockerignore` (in repo root) to keep build context clean
  - Amend `autogpt/docker-compose.yml` and all `autogpt-docker-*.yml` workflows accordingly

- Include `forge/` in docker build context so it can be used as a path dependency

- Include `frontend/` in docker builds
