- Implemented 2FA management in admin panel with enable/disable options.
- Added QR code display for 2FA setup and input for TOTP codes in login and pickup forms.
- Introduced key management section for generating, loading, and clearing RSA key pairs.
- Enhanced file upload and sharing functionality with optional 2FA.
- Added buttons for switching between development and production modes in admin panel.
- Updated API documentation to reflect new 2FA and key management features.
