Replace crypto tests with comprehensive unit tests for authStore, storage, and configuration modules

- Removed outdated `crypto` tests; added dedicated and structured tests for `authStore`, `storage`, and `app.config`.
- Enhanced test coverage for user and token validation, secure persistence, state management, and configuration parsing.
- Consolidated encryption and storage error handling with thorough validation to ensure SSR-safety and resilience.
- Improved runtime validations for tokens and configuration with stricter type checks and fallback mechanisms.
