test: add storage coverage (firebase contract, factory), silence scenario log

- firebase.contract.test.js: run storage contract against createFirebaseStorage
  via SDK mock. Currently 12 fail (firebase diverges from contract: no norm(),
  injects id). Failures real — firebase copied from main, memory/ws invented
  new requirements. Contract under review vs main prod truth.
- storage.factory.test.js: getStorage() routing per REACT_APP_STORAGE env,
  singleton cache, getStorageMode() reporting.
- Combat.scenario.test.js: remove console.log (test noise).
- package.json: test:all now runs App + shared + server suites (was missing App).
