feat(payments): add Order & Escrow repository tests, prisma config, docs

Add 26 unit tests for PrismaOrderRepository and PrismaEscrowRepository covering CRUD operations, pagination, domain mapping (bigint → Money), idempotency key lookup, and escrow dispute workflow fields. Update prisma.config.ts with dotenv import and seed command for Prisma 7. Add architecture summary and codebase overview documentation files. Co-Authored-By: Paperclip <noreply@paperclip.ing>
