test(cabana): Plugins screen endpoints

- TestPluginsEndpoints: 401/403/200 for both endpoints, the update rule
  table, cache hit and expiry on an injected clock, failure caching, at
  most 4 version lookups at once, call timeout, marketplace validation,
  markers, https-only icons, disabled registry making no call
- fix: marketplace categories come only from plugins the screen offers,
  not from registry entries dropped for an invalid ID
- check-phase34.sh: TestPluginsEndpoints and useSettings.test.ts required
