iOS - Files - Moving a file into the same folder shows an untranslated internal error message (code 403)

Actions Performed
1 .Open the app.
2. Navigate to any folder containing at least one file.
3. Tap the three-dots menu (… → “Verschieben oder Kopieren” / “Move or Copy”) on a file.
4. Choose the same folder as the source as destination.
6. Tap “Verschieben” (“Move”) to confirm the action.

Expected Result
Display a properly localized German error message, clear and user-friendly, explaining that the source and destination are identical :
“Quelle und Ziel sind identisch.”
(“Source and destination are identical.”)
“Die Datei befindet sich bereits in diesem Ordner.”
(“The file is already in this folder.”)

Actual Result
An untranslated internal system error appears in English:
“Source and destination uri are identical., code: 403”
The error is not localized, not formatted correctly, and looks like an internal debug string.

Error Message
“Source and destination uri are identical., code: 403”

Start by reproducing the iOS Files move/copy flow described in the issue, moving a file into its current folder and observing the 403 message. Trace that flow to the localization or error-display entry point. Done means the German message is localized, user-friendly, and no longer exposes the untranslated internal error string.
