Remove old configuration, API client, and redundant crypto mocks

Browse Source 
- Deleted legacy `config` module and replaced its usage with the new runtime-validated `app.config`.
- Removed old custom Axios `apiClient` with outdated token refresh logic.
- Cleaned up redundant crypto-related mocks in storage tests and replaced them with real encryption/decryption during testing.
- Updated Jest coverage exclusions to reflect the new file structure and generated client usage.
