test: complete Wave 3 - Mock Library (6 tasks, 15+ Mock factories)

Wave 3: Mock Library Implementation ==================================== **Mock Factories (15+ total)**: - Logger/ConfigManager (createMockLogger, createMockConfigManager) - ErpAuthService (createMockErpAuthService with isLoggedIn/loginFails options) - TypeORM/Database (createMockDataSource, createMockRepository, createMockDatabaseService) - Electron/IPC (createMockElectron, createMockIpcRenderer) - Utility modules (createMockFs, createMockPath, createMockExcelJS, createMockAxios, createMockChildProcess, createMockCrypto) **Files Modified/Created**: - tests/mocks/types.ts: +243 lines (Mock type definitions) - tests/mocks/index.ts: +475 lines (Factory function implementations) - docs/MOCK_LIBRARY_USAGE.md: 197 lines (Usage guide with 12+ examples) - tests/unit/mocks/electron-ipc.test.ts: 12 tests (Electron/IPC Mock verification) **Quality**: - Zero any types - All Mocks ≤20-30 lines - Complete JSDoc documentation - All factory functions support overrides customization **Total Progress**: - Wave 1: 4/4 ✅ - Wave 2: 5/5 ✅ - Wave 3: 6/6 ✅ - Overall: 15/34 ✅
