Bundle mission-control into Triple-C instead of cloning from GitHub

The mission-control (Flight Control) project is being closed upstream.
This embeds the project files directly in the repo under container/mission-control/,
bakes them into the Docker image at /opt/mission-control, and copies them into place
at container startup instead of git cloning from GitHub.

Also adds missing osc52-clipboard, audio-shim, and triple-c-sso-refresh to the
programmatic Docker build context in image.rs.
