Media App: Insights Page Table Sorting

[zcolah]

Problem Currently the Insights table is not in any sorted order. Furthermore we can sort the table by any of the available columns. This does not match the expectations set in the spec.

Solution Please set the default sort of the table in the insights page to be in descending order of requests. This means the image with the most requests will be first and so on.

Furthermore please ensure each of the columns can be sorted as specified in the spec here: https://www.figma.com/file/pBgVbMZSItzqRYcEXg2lhe/Media-App?node-id=2253%3A171851&t=PwKhUTRk0YJqHRkE-1
