/**
 * Mock Type Definitions for ERPAuto Unit Tests
 *
 * This module provides strongly-typed Mock interfaces and factory function signatures
 * for all core services that need to be mocked in unit tests.
 *
 * Design Principles:
 * - Zero any types - all mocks are fully typed
 * - Use vi.fn() mocks for all methods
 * - Factory functions accept Partial<T> overrides for customization
 * - JSDoc comments on all types and functions
 *
 * Usage:
 * - Import types from this file in test files
 * - Use vi.fn() to create mock implementations
 * - Factory functions provide sensible defaults
 *
 * Note: This file defines standalone mock types compatible with src/main interfaces.
 * Import actual Config/Logger/Erp types from src/main in test files when needed.
