Refactor storage handling across application

- Introduced a new storageHelpers module to centralize localStorage interactions, improving code maintainability and readability.
- Updated various components and managers to utilize the new storageHelpers functions for setting, getting, and removing items from localStorage.
- Added migration logic to handle localStorage items during application initialization, ensuring compatibility with the new storage structure.
- Enhanced logging during application initialization for better debugging.
