Fix priority logic for appeals with aod motions for distributions

[hschallhorn]

Description

Now that AOD motions should be associated with an actual appeal (#14085), we need to adjust the logic for what we consider priority for distributions. This is still looking for motions associated with the claimant that were created after the appeal was established.

caseflow/app/models/docket.rb

Lines 106 to 113 in aec6a6a

	def priority
	join_aod_motions
	.where("advance_on_docket_motions.created_at > appeals.established_at")
	.where("advance_on_docket_motions.granted = ?", true)
	.or(join_aod_motions
	.where("people.date_of_birth <= ?", 75.years.ago))
	.group("appeals.id")
	end

Acceptance criteria

• Priority ama appeals are pulled for distribution ONLY if one of the following are true
  • aod_based_on_age is true on the appeal
  • The claimant's dob is over 75 years ago
  • The claimant has a granted age base aod motion
  • The appeal has a granted aod motion associated with the appeal
  • The appeal is a cavc remand (not yet implemented)
• Scope is created for appeal model that captures all this with no N+1 queries (should only produce one db call if possible)

Notes

The first 3 AC have a lot of overlap. What should we consider as our source of truth as I assume we don't want to check all 3?

what is this chart?

1 | 
2 | |||||
3 | ||||
5 | 
8 | 

Maybe a helper function to answer the requirements? Not sure where it would go though.

Why 1?

Why 2?

• Well scoped change

Why 3?

• Testing various scenarios for each permutation of the boolean logic checks
• AOD has historically been a little tricky
