sort filter in crud_router for auto-generating endpoints

[mohit-chaniyal]

Is your feature request related to a problem? Please describe.

When using the crud_router for auto-generating endpoints, I noticed that while pagination and filtering are supported, there is currently no built-in way to sort the results. This makes it difficult to order query results by fields like created_at, username, or any other attribute, which is a common need in APIs.

Describe the solution you'd like

I'd like to request native support for sorting query results via query parameters in the read method of crud_router. For example:
GET /users?sort=created_at
GET /users?sort=-username # descending
