Add extensive form tests and enhanced error handling for auth components.

Browse Source 
- Introduced comprehensive tests for `RegisterForm`, `PasswordResetRequestForm`, and `PasswordResetConfirmForm` covering successful submissions, validation errors, and API error handling.
- Refactored forms to handle unexpected errors gracefully and improve test coverage for edge cases.
- Updated `crypto` and `storage` modules with robust error handling for storage issues and encryption key management.
- Removed unused `axios-mock-adapter` dependency for cleaner dependency management.

* Comprehensive tests for API client wrapper with interceptors
* Tests for API client configuration

* Tests cover:
* - Client configuration
* - Request interceptor (Authorization header injection)
* - Response interceptor (error handling)
* - Token refresh mechanism
* - Token refresh singleton pattern (race condition prevention)
* - All HTTP error status codes (401, 403, 404, 429, 500+)
* - Network errors
* - Edge cases and error recovery
* Tests ensure the client module loads and is configured correctly.
* Note: Interceptor behavior testing requires actual HTTP calls, which is
