refactor(auth): enforce authorization checks across livewire components

Add authorization checks to multiple Livewire components to ensure users
have proper permissions before performing sensitive operations. This includes:

- Adding AuthorizesRequests trait to components handling deployments, backups,
  services, and configuration uploads
- Enforcing 'deploy', 'update', and 'manageBackups' authorization checks
- Adding instance admin check for system upgrade operations
- Improving database queries with team ownership scope
- Moving backup trigger from component to button with new backupNow() method
