Refactor: Remove passkey-related functionality and types

- Deleted passkey-related interfaces and types from index.ts and types.ts.
- Removed passkey handling from App component, including related state and functions.
- Cleaned up API calls in auth.ts, removing passkey registration and login functions.
- Updated vault and import formats to eliminate passkey references.
- Removed passkey support checks and UI elements from AuthViews and SettingsPage.
- Cleaned up unused passkey helper functions and constants.
- Adjusted related components and hooks to ensure consistent functionality without passkey support.
