[API]: Refactor middleware logic

[NikSimDev]

Change Type

Performance improvement

Current API

No middleware
We need:

• request logging
• rate limiting
• auth guard
• body size limit
• CORS

Proposed API

app.use(cors());
app.use(jwtAuth());
app.use(requestLogger());

Rationale

Currently, CORS is a separate method in the controller, which is not very convenient. In a modern framework, middleware is a must-have.

Migration Path

No response

Backward Compatibility

Potentially full Backward Compatibility.
