The Dockerfile, docker/Dockerfile.non_root and docker/Dockerfile.database uv sync stages never passed --extra bedrock-realtime, so aws-sdk-bedrock-runtime was absent from the image venv and Bedrock Nova Sonic /v1/realtime sessions failed with 'Missing aws_sdk_bedrock_runtime'. gateway/Dockerfile already had the extra (PR #34426).
Adds a static check over every uv sync in the proxy Dockerfiles and an image-level import probe that the image-scan workflow runs against the built root, non-root and gateway images.
