Subject: [PATCH 1/4] feat: add social likes facet to package trends charts

Generalize the download analytics chart into a trends chart that supports both downloads and likes,
extensibly allowing for more facets in the future.

- Add a facet selector (Downloads / Likes) shown on Compare page and in the single-package chart modal
- Add server endpoint and utility for fetching per-package likes evolution from ATProto
