bulk validation etc

• https://api.datamermaid.org/v1/projects/<project_id>/collectrecords/ [GET] -- get a list of CRs for a project. Each CR contains a validations object, which has a status property as you saw that can be used to provide summary feedback.
• https://api.datamermaid.org/v1/projects/<project_id>/collectrecords/validate/ [POST] -- submit a list of CRs for validation. Payload is like:
  {
  "ids":["17f8dae9-7f2d-41e1-a093-d7dd5307534b"]
  }
  As you can see, this supports multiple CRs; but I suggest that we keep it to one per call for now.
• https://api.datamermaid.org/v1/projects/<project_id>/collectrecords/submit/ [POST] -- attempt to submit a list of CRs, with the same payload structure. Same instinct here on submitting one at a time for now.
