feat: improve API key encryption reliability across environments

- Added safe electron import with fallback for non-electron environments
- Enhanced error handling when safeStorage is unavailable
- Updated encryption checks to handle cases where safeStorage is null
- Added warning message when API keys must be stored in plaintext
- Modified isEncryptionAvailable to check for both safeStorage existence and capability
