Merge: Multi-Feature Integration Branch

Overview

Consolidated merge of four feature branches into a single integration branch containing comprehensive test suites and feature implementations for the escrow lifecycle, delivery QR code verification, event indexing, and real-time socket location tracking.
Closes #20 (QR code delivery verification)
Closes #39 (Escrow event indexer handlers)
Closes #110 (E2E escrow lifecycle tests)
Closes #111 (Socket.io location event tests)

Merged Branches

1. Issue #110: E2E Escrow Lifecycle Tests

Branch: test/e2e-escrow-lifecycle

Complete end-to-end test suite for escrow workflow with 40+ test cases covering:

Step-by-step escrow creation, funding, and release
Query operations by delivery/contract ID
Error scenarios (400, 401, 404, 409 responses)
Idempotency verification with Idempotency-Key header
Real MongoDB (MongoMemoryServer) with Soroban mocks

Files Added:

tests/e2e/escrow.test.ts (673 lines)
tests/e2e/helpers/db.ts (47 lines)
tests/e2e/helpers/auth.ts (75 lines)
tests/e2e/helpers/soroban.mock.ts (97 lines)

2. Issue #20: QR Code Delivery Verification

Branch: feat/delivery-qrcode-verification

New QR code endpoint for secure delivery handoff verification with:

Secure token generation (256-bit entropy via crypto.randomBytes)
Token scoped to ASSIGNED/IN_PROGRESS status with 24h expiry
Base64-encoded PNG QR code containing deliveryId + token
Full OpenAPI documentation
40+ test cases with comprehensive error coverage
Strict Controller→Service→Model layering

Features:

GET /api/v1/deliveries/:id/qrcode endpoint
MongoDB persistence for token verification
TypeScript strict mode compliance

3. Issue #39: Escrow Event Indexer Handlers

Branch: feat/indexer-escrow-resolved

Implement indexer handlers for escrow_released and escrow_refunded events with:

Event parsing and validation (parseEscrowReleasedEvent, parseEscrowRefundedEvent)
Event handlers with batch processing (handleEscrowReleasedEvent, handleEscrowRefundedEvent)
Distributed Redis locking for race condition prevention
Idempotent operations via transaction hash tracking
State machine enforcement: LOCKED → RELEASED/REFUNDED (terminal states)
Full audit trail in transactions array

Features:

refundEscrow() service method with distributed locking
RefundEscrowInput interface for refund operations
Status updates with proper timestamps
Related delivery status synchronization (COMPLETED/CANCELLED)
Comprehensive error handling with AppError
Debug/info/warn/error logging throughout

Files Added/Modified:

src/indexer/escrowHandlers.ts (+286 lines, 1 modified)
src/services/escrow.service.ts (+121 lines)
tests/integration/escrowHandlers.test.ts (589 lines)

Test Coverage: 30+ integration tests with MongoMemoryServer, idempotency verification, state machine transitions, and edge case handling.

4. Issue #111: Socket.io Location Event E2E Tests

Branch: test/socket-location-events

Comprehensive E2E integration tests for real-time driver location tracking with 35 tests across 9 suites:

Test Suites:

Socket Connection (4 tests)
Delivery Room Joining (3 tests)
Location Update Events (6 tests)
Deduplication & Race Conditions (3 tests)
