Function ResolveActiveFileStorageProviderId

ResolveActiveFileStorageProviderId(
contextUser: UserInfo,
provider: IMetadataProvider,
): Promise<string>
Resolve the id of the first active MJ: File Storage Providers row, or null when none is active. The provider id is stamped on every artifact's MJ: Files row (its ProviderID is NOT NULL); a seeded active provider (e.g. "Local Storage") is what lets MJFilesArtifactStore create a valid File row in dev / on-prem deployments.
Parameters
- contextUser: UserInfo
  the acting user (server-side data access is user-scoped)
- provider: IMetadataProvider
  the provider the read runs on (no global fallback)
Returns Promise<string>
the active provider id, or null when none is active
