Implement pagination on transfer job listing

[nathanthorpe]

Resolves #385. This PR adds pagination to the transfers pane at the top.

• Pagination buttons do not show if there is only one page
• When there are between 2 - 5 pages it shows a simple selector.
• When there are more than 5 pages it shows a selector with first/last/ellipses/etc depending on what page you are on.

Note that the copy-jobs list endpoint sends back a different model to include page information.

It includes the option to specify the page size in the API but that is not exposed in the UI.
