fix(upload-list): handle conflict actions

[alperozturk96]

Issue

On Android, we are showing conflicts based on the stored last upload result, but this is wrong because the server can change at any moment. As a result, we may display an incorrect status, and the user might try to open the conflict resolution dialog even though it’s unnecessary, perhaps the file no longer exists on the remote server or has been moved.

Flow

First check remote path from OCUpload via ReadFileOperation -> if file not there remove conflict error and allow user to retry upload

If file exists on remote and same -> if file not there remove conflict error and allow user to retry upload

If file exists and different -> show conflict resolve dialog

Changes

• Extracts isSame logic since its necessary for this PR as well.
• Implements UploadListAdapterHelper, UploadListAdapterAction since needed for handling conflicts and not bloating the adapter logic. Also we need to implement other actions as well in future.
• Adds correct messages that reflects current state of the upload and action.
• Adds UploadFileOperationFactory since huge constructor needs to be repeated for each file
