Catalogue search loads matches past the first 200 cards, so a query such as one with 258 matches is not cut off at 200. Sorting searches larger than 800 results still needs server-side sort and dir before limit and offset; that API change is not in this pull request.

Merged into app staging in #896 as df04b4bfccd404f100fd4b4c6c3d25be4f2dfaa2. Not deployed. Local gates only.
