Feature Flag Registry Check

This PR introduces feature flag references that are not yet registered in the
feature flag registry.

Unregistered flags

Flag	Referenced in
moneyAccounts	app/core/Engine/controllers/money-account-service/money-account-service-init.ts

How to fix

Add an entry for each flag in tests/feature-flags/feature-flag-registry.ts:

myNewFlag: {
  name: 'myNewFlag',
  type: FeatureFlagType.Remote,
  inProd: false,
  productionDefault: false,
  status: FeatureFlagStatus.Active,
},

Set inProd and productionDefault to match the current production values from the
client-config API.

If you access the flag via a constant (e.g. remoteFeatureFlags[MY_CONSTANT]), also add the constant to
.github/scripts/known-feature-flag-constants.ts
so the CI check can resolve it.
