Subject: [PATCH] Default the Docker footer branch to main

Production only deploys main, so default ARG GIT_BRANCH=main. The image
now bakes the branch with no Coolify config (overridable per-branch via
--build-arg). Verified in a real docker build that the branch and the
shortened SOURCE_COMMIT land in the server binary.
