The first click did nothing because instant_remote_process() blocked the
Livewire response, preventing UI state updates. The button also remained
visible during download, allowing multiple clicks.
- Replace blocking instant_remote_process() with async command in queue
- Add container cleanup to command queue with error suppression
- Hide "Download & Prepare" button when s3DownloadInProgress is true
- Button now properly disappears when clicked, preventing double-clicks
- No more blocking operations in downloadFromS3() method
