These tests lagged behind two refactors:

- build_studio_catalog is now an async coroutine. Update the studio tests to
  await it: direct-call tests wrap it in asyncio.run(), and the HTTP tests'
  monkeypatched stubs are now async (the route handler awaits the result, so a
  sync stub returning a dict raised "object dict can't be used in 'await'
  expression").
- The providers page bootstraps provider data from a dedicated JSON <script>
  element (providers_bootstrap_json, escaped by the route's _json_parse_bootstrap
  helper) parsed via JSON.parse, instead of an inline `let providersData = {...}`
  literal. Update the admin bootstrap test to feed providers_bootstrap_json and
  assert on the <script id="providers-bootstrap"> element (escaping + double
  JSON decode) and the JSON.parse usage.
- Add the missing record_dashboard_event method to MarketReferenceImportDbStub,
  which the market import route now calls.

tests/routes now passes 86/86 (was 18 failing).
