fix: add authorization checks to database Livewire components

Added authorization checks to 11 database-related Livewire components
that were loading sensitive database configuration without verifying
user permissions.

Changes:
- Added authorize('view', $database) to all 8 database type General.php mount() methods
- Added authorization to Configuration.php before loading database
- Added authorization to BackupEdit.php before loading backup config
- Added authorization to Import.php before loading database resource

This prevents unauthorized users from accessing database credentials,
connection strings, and configuration details.
