kernelsu-antibootloop-and-b…/kernelsu_antibootloop_backup/scripts/backup-encryption.sh
Wiktor a87e4b33c1 feat(settings): add comprehensive settings application script 
- Introduce apply-settings.sh to apply and validate module settings
- Manage WebUI, backup, safety, system, and notification configurations
- Support automatic backup scheduling and safe mode configuration
- Include settings validation and default settings creation
- Enhance module configuration management and logging
