Adds a "Git Sync" section in the Integrations rail panel that lets project owners configure an HTTPS remote URL (with embedded auth token) and force-push all project files as a single commit. Backend: - GitSyncHandler: assembles project docs + binary files into a temp dir, runs git init/commit/push --force, then cleans up - GitSyncController: GET/POST /project/:id/git-sync (configure), POST /project/:id/git-sync/push (trigger) - Project model: gitRemote field - Dockerfile: ensures git is present at runtime - Env flag: OVERLEAF_ENABLE_GIT_SYNC=true (set in k8s manifest) Frontend: - GitSyncWidget: URL input + Save + Push Now buttons, success/error feedback - Integrations panel: shows widget when gitSyncEnabled - Rail: shows Integrations tab when gitSyncEnabled (was only gitBridgeEnabled) - i18n: en + fr translations Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
