Implement serialization/deserialization and persistent storage across services

- Add serialize/deserialize support for core models - Add file-based load/save functions in management services - Introduce FileManager, Config, Utility and helper utilities - Persist observer IDs for notification services - Resolve object relationships during load (services, bookings, invoices, job cards) - Add controller-level loadSystemData/saveSystemData - Load data at app startup and save on shutdown
