Combines shared, blog, market, cart, events, federation, and account into a single repository. Eliminates submodule sync, sibling model copying at build time, and per-app CI orchestration. Changes: - Remove per-app .git, .gitmodules, .gitea, submodule shared/ dirs - Remove stale sibling model copies from each app - Update all 6 Dockerfiles for monorepo build context (root = .) - Add build directives to docker-compose.yml - Add single .gitea/workflows/ci.yml with change detection - Add .dockerignore for monorepo build context - Create __init__.py for federation and account (cross-app imports)
