Implement several new features and improve SAF integration

This commit implements the following features:
- Trash/Archive for deleted entries
- Duress Password (Decoy Vault)
- Advanced Sorting and Usage Insights
- Improved Storage Access Framework (SAF) Integration

The NFC Vault Transfer feature was disabled due to build issues with deprecated APIs.
