remove /api/entities/get_raw_page endpoint

[Joao-vi]

Changes

It was deleted the /api/entities/get_raw_page because is not used anymore in code base and also it was calling entites.getRawPage as data source, the problem is that getRawPage is not even declared on entities object.

I believe this feature was moved from /api/entities/get_raw_page to api/documents/page because the front-end code is still using getRawPage but pointing to api/documents/page

  async getRawPage(requestParams) {
    const response = await api.get(
      'documents/page',
      requestParams.add({ page: requestParams.data.page || 1 })
    );
    return response.json.data;
  },
