ENSAnalytics endpoint that would support pagination through referrals made by specific address

[Goader]

Background:

• ENS Holiday Awards needs a "Referrer Detail" page, that will display the referrals statistics for a given address.
• Follows feat: introduce ENSAnalytics API into ENSApi #1239 and ENSAnalytics endpoints with detailed statistics for a specific address #1262
• It is now unblocked with feat(ensindex): introduce registrars plugin #1249 already merged into main.

Subtasks:

• Implement API that supports pagination through all the referrals made by a specific referrer

Note that this will not use cache, and therefore execute queries to the ENSDb for every request.

@tk-o Hey could you share your advice here?

Our goal is to advance a Referrer Detail page on ENSAwards where we want to support pagination through all registrar actions made on subregistry X by decodedReferrer Y, sorting by timestamp desc.

It seems we should be able to achieve this goal through just a few small adjustments to this existing API?

Assuming so, could you assign this issue to yourself and take the lead on it for us? Many thanks!

My understanding is we need to update this API to add support for the following:

1. We need to add an optional filter for referrer. This should take an Address as input and filter the decodedReferrer field in the database.
2. We need to add pagination. Pagination should be implemented using the exact same param names and pagination strategies as we implemented for the leaderboard API.
