fix(precedents): separate court rulings from committee decisions correctly

- DB: add 'all_committees' virtual source_kind covering internal_committee
  + external_upload appeals_committee rows in one query
- DB: stats now count all case_law rows (not just external_upload),
  fixing the precedents_total that excluded 44 internal-committee records
- UI: courts table filters to source_type=court_ruling only;
  committees table uses the new all_committees query
