🐛 Fix multiple custom rules upload (konveyor#2636)

Resolves: https://issues.redhat.com/browse/MTA-6029
Resolves: konveyor#2654

When uploading multiple custom rules in analyzer wizard, only last one
was corectly processed for it s rules, updating code to make sure each
uploaded file processed.

Used claude code to assist with this change.

## Summary by CodeRabbit

* **New Features**
* Rule files now begin processing immediately after selection with
initial progress/status visible.
* Each file carries its own per-file context through the upload
lifecycle for clearer handling and callbacks.

* **Bug Fixes**
  * Upload progress and status updates are more consistent and visible.
* Success and error callbacks reliably map to the correct file,
preventing stale state and improving error attribution.
