feat: add S/MIME store for managing key records and public certificates

- Implemented Zustand store for S/MIME functionality, including state management for key records and public certificates.
- Added methods for importing PKCS#12 files and public certificates, binding identities to keys, and managing unlocked keys.
- Introduced session storage for remembering unlocked keys across sessions.
- Enhanced error handling and loading states during data operations.
