chore: optimize Dockerfile apt source compatibility and update edge.yaml cloud/ota URLs to port 9000

- Dockerfile: support both legacy sources.list and DEB822 format for apt mirror
- Dockerfile: use official python:3.9-slim instead of Huawei Cloud SWR mirror
- .dockerignore: exclude !build/edge-agent to avoid build artifact in context
- edge.yaml: change cloud_url from 8004 to 9000 (stream-gateway)
- edge.yaml: change ota_url from 8087 to 9000
- Add Dockerfile.bak and buildkitd.toml
