Generate an OpenAPI 3.0 spec from route annotations and serve it with
Swagger UI so the full REST API is browsable and testable.
- Add swagger-ui-express (runtime) and swagger-autogen (dev) deps, plus
an `npm run swagger` script.
- server/swagger/swagger.js: generator config with API metadata, servers,
14 tag groups, cookie + bearer security schemes, and 28 reusable
component schemas. Follows the Express mount chain from src/app.js so
generated paths are fully-qualified (/api/v1/...).
- Annotate every route (auth, mobile, sso, public, admin, health) with
#swagger tags/summaries/parameters/request bodies/security and the
actual response codes each handler returns (400/401/403/404/409/429/
302/502, multipart uploads).
- Serve Swagger UI at /api/docs and the raw spec at /api/docs.json,
guarded so a missing spec disables docs instead of crashing.
- Commit the generated swagger-output.json so docs work with no build
step; swagger-autogen stays dev-only and is not needed at runtime.
- README: new "API documentation (Swagger)" section plus tech-stack and
project-structure entries.
Covers 51 paths / 64 operations. Existing test suite (83) still passes.
