feat: enhance backup functionality and logging

- Updated `createBackup` method to accept a `force` parameter, allowing backups to be created even if no changes are detected.
- Added user alerts in `AdvancedSettingsPageClient` and `BackupSettingsPageClient` for backup status feedback.
- Implemented `getBackupLogs` method in `BackupService` to retrieve backup logs, with a new API route for accessing logs.
- Enhanced UI in `BackupSettingsPageClient` to display backup logs and provide a refresh option.
- Updated `BackupManagerCLI` to support forced backups via command line.
