feat(search): multi-select quick filters for search results and site releases (SEARCH-3)

- domain release-facets: bucket resolution / codec / release type / site / promotion / HDR /
  release group / season / episode; OR within a dimension, AND across; disjunctive counts
- GET /search/releases and GET /sites/{id}/releases accept qf and return facets; site list
  facets come from local source_release rows only (no site requests), paging stays consistent
- web QuickFilterBar shared by search results and site resources tab: per-dimension popover
  (bottom sheet on phones) with counts, removable tags, clear all, localStorage memory per page
- runbook: quick filter params and bucket definitions
