fix: pass git commit hash as Docker build arg so footer shows correctly

git is not available inside the node:20-alpine Docker image, so
git rev-parse in next.config.ts falls back to 'dev'. Now the commit
hash is passed as a COMMIT_HASH build arg from the host where git
is available, ensuring the footer displays the real commit hash.
