Add pagination to the job list API

[huzjie]

Goal

The GET /api/jobs endpoint returns all jobs. Add page / page_size parameters with a stable order.

Good first issue

• Mirror the pagination style used elsewhere in the codebase.
• Return {items, total, page, page_size}.

Acceptance criteria

• Paginated responses and a test for page boundaries.

Hi @huzjie! I would love to work on this.

I'll check out the existing pagination style in the codebase to make sure the implementation is consistent. I will add the page and page_size parameters to the GET /api/jobs endpoint, ensure it returns the {items, total, page, page_size} format, and write the required tests for the page boundaries.

Could you please assign this to me?
