fix(api): add Request parameter to process_url endpoint for session access

The @require_login decorator expects a Starlette Request as the first
parameter to access request.session, but process_url only had a
URLUploadRequest Pydantic model parameter. This caused an
AttributeError: 'URLUploadRequest' object has no attribute 'session'
when POST /api/process-url was called.

Fix: Add `request: Request` as the first parameter and rename the
Pydantic model parameter from `request` to `url_request`.
