Validate document_id when checking if a decision has been written for a case

[hschallhorn]

User story

As an AVLJ, I need to see attorney actions on legacy cases assigned to me, so that I can draft decisions. As of right now, if the document id on the appeals associated decass record is anything other than nil, acting judges are shown judge actions. On occasion, this value will read "NONE". We should instead validate that the document id is valid, not just that it exists.

Acceptance criteria

• Check document_id is valid before returning true

Out of scope

Further work to better determine what actions to show an AVLJ will be done. This issue is to only solve the issue that arose from invalid document ids.

Background/context

Allow AVLJs to be assigned legacy cases #11971
Allow AVLJs to perform judge tasks on legacy appeals #11977
Use the presence of a decision doc id to determine if a case has already gone to an attorney #13530

Technical notes

We already do validation of document ids on attorney checkout here. This could be reused.

Based on when Doc ids are pulled from DAS, which might not be done in Caseflow, so its not validated by us.
Only affects legacy appeals. Where we pull in cases from vacols for a users legacy queue.

Estimating at a 3.

Might be simple as the location is well known, just have to update the value.
