Changes

Fix cancel upload
Add remove upload

This update improves the handling of file uploads by clearly distinguishing between Cancel and Remove actions:

Cancel Upload:

1. Stops the current upload in progress.
2. Marks the upload as cancelled.
3. The upload remains visible in the upload list.
4. On app restart, cancelled uploads automatically resume.

Remove Upload:

1. Deletes the upload from the upload list entirely.
2. The file will never be uploaded again.

These two actions provide necessary functionality for managing uploads, especially in cases such as SYNC_CONFLICT, where users need to either resolve the conflict or remove the upload.

This update also ensures that users can clearly distinguish between cancelling an upload and permanently removing it, reducing confusion and improving overall upload management.

blue-Light-Screenshot test failed, but no output was generated. Maybe a preliminary stage failed.

I guess this is merged now, but more accurate terms would be:

Cancel → Pause and
Remove → Cancel

as "cancel" sounds final.

[kra-mo]

Although the first one could also be called "Stop" and the second could remain "Remove". Whatever you think makes more sense with the rest of the feature's existing wording.

@kra-mo I will create another PR for that, thanks.
