build: pin swag CLI and oauth2-proxy, ignore build artifacts in docker context (apache#8989)

Make the backend container build inputs reproducible and shrink the
Docker build context:

- Align the swag CLI pin to v1.16.6 across backend/Makefile,
  backend/Dockerfile and backend/Dockerfile.local so local, CI and
  image builds generate Swagger docs with the same tool version.
- Pin the oauth2-proxy dev auth proxy image to v7.15.3-amd64 in both
  docker-compose-dev-mysql.yml and docker-compose-dev-postgresql.yml.
- Add backend/.dockerignore to keep regenerated build artifacts
  (bin/, mocks/, logs/, Python venv/build output, coverage files and
  OS junk) out of the build context. Source under python/ is retained.

No functional/runtime code changes.
