feat: Enhance JSON configuration writer and add heartbeat recording to crash recovery service

- Updated JsonConfigWriterService to structure the JSON output with new sections for scripts, window settings, input bindings, paths, rendering, and GUI configurations.
- Introduced a new method in ICrashRecoveryService to record frame heartbeats, allowing for better tracking of long-running operations.
- Refactored existing code to improve readability and maintainability, including the addition of helper functions for adding string members to JSON objects.
