69 - Add Opportunity Plan roll-up to Master Account Plan

Add an aggregate view of CRUSH Opportunity Plan records (PQ_Opportunity_Plan__c) on the Master Account Plan so portfolio owners can see deal-level plans across child Account Plans — additive UX that does not replace or change the existing Account Opportunities (standard Opportunity) table already on the Master Account Plan Strategy tab.

User story
