vectorStoreFiles(after = ...) uses VectorStoreId instead of FileId

[BlackBaroness]

Looks like the API contract here is not correct, since it's just not possible for VectorStoreId to be here. We iterate files inside the one single specific vector store

public suspend fun vectorStoreFiles(
        id: VectorStoreId,
        limit: Int? = null,
        order: SortOrder? = null,
        after: VectorStoreId? = null, // this
        before: VectorStoreId? = null, // and this
        filter: Status? = null,
        requestOptions: RequestOptions? = null,
    ): List<VectorStoreFile>

I believe it should receive VectorStoreFile.id (FileId) here.
