fix: remove limit on record sets in search dialog

[grantfitzsimmons]

Fixes #6971

Contributed by @foozleface

The Record Sets button in the Search Dialog used usePaginator with a default limit of 10 (configurable in the record sets dialog) but never rendered the paginator UI, so users could only see the first 10 record sets. Replace with limit: 0 to fetch all record sets for the current user.

  self-explanatory (or properly documented)

• Add automated tests

Testing instructions

Make sure you have a large number of record sets for the base table so you can exceed the limit set in the record sets dialog easily. I tested this in situations with hundreds of record sets, and it should become scrollable with that many.

• Set the limit on the number of record sets per page to 10 in the Record Sets dialog

• Go to a place where you can search or select a record set (e.g. by clicking the plus in the collection relationship plugin), and select record set, and verify that all record sets of the appropriate base table appear

Works as expected. I was able to see all the possible record sets.

Looks good!
