Coolify v4 doesn't inject SOURCE_COMMIT (only COOLIFY_BRANCH,
COOLIFY_FQDN, COOLIFY_RESOURCE_UUID, COOLIFY_URL and the container
name). The previous build-arg approach always resolved to "dev".
Switch the web build context to the repo root so the Dockerfile can
COPY .git into a scratch path, parse HEAD → SHA with a small sh
snippet (handles both detached-HEAD and packed-refs), and stamp the
image with a /git_commit file. settings.py now prefers env GIT_COMMIT
(for local dev overrides) and falls back to /git_commit → "dev".
The .git copy is the last content layer, so only this thin layer
invalidates per commit; pip install stays cached.
