feat(logging): Wave 2 - integrate logging throughout application

This commit integrates the logging infrastructure across the entire application:

IPC Layer:
- Add logger-handler.ts with centralized IPC logging channels
- Integrate audit logging into auth, cleaner, extractor handlers
- Add structured logging for IPC operations and data flow

Service Layer:
- Add logger integration to ERP services (extractor, cleaner)
- Integrate logging into excel-parser and user DAO
- Add operation tracking and error logging

Renderer Layer:
- Add useLogger hook for component-level logging
- Update App.tsx with session and user activity logging
- Enable frontend audit trail for critical actions

Testing:
- Add comprehensive IPC logging integration tests
- Enhance unit test coverage for logger and audit-logger
- Add end-to-end logging flow validation

Types:
- Update preload type definitions for logging APIs
