Creating or renaming duplicate file/folder throws inappropriate message [M]

Step to reproduce

1. Launch the NextCloud app
2. Create two folder with the name " Folder A" and "Folder B"
3. Now rename Folder B to Folder A-"that is already exists"
4. Create two new text document file and rename the file which is already exist
5. Also create the duplicate folder or file name- which is already exists

Actual result
For renaming the already existing file/folder name- it throws a message "412: The server does not meet one of the precondition that the requester"
For Creating the already existing file/folder name- it throws "File conflict" dialog for file. For folder it will create by adding number increasing order
ex. if there is folder "test" and create the folder again with the same name so it will be created named as "test 1"

Expected result
It should throw a message like- "file already exists" in English in both the case

Start by reproducing the duplicate-file and duplicate-folder rename and creation flows in the Nextcloud iOS app, then trace the handling of the 412 response, file-conflict dialog, and automatic folder naming. Done means duplicate files and folders consistently show an English “file already exists” message.
