Bug description

According to client management the functions for deleting a user are not correctly handled.

-1-
If you delete a user clients get a 401 http error (JSON internal error 997) we are then forced to block the flow, delete the password and immediately request new credentials, which would practically also mean deleting the internal files as server-side, otherwise one would not understand why deleting a user and leaving the data within the client would take up so much space on the phone.

So you don't understand the real difference between delete user and wipe all devices

-2-
Disabling the user should be momentary, so that temporarily the client no longer has access to the server (although it can still consult the local data?). But on the client side there is no difference between Delete user and Disable user (error 401 JSON error 997) which would still mean having to request credentials with the login mask.

-3-
For more than a few customers, it happens that the user on his phone inexplicably receives a 401 and is forced to log in, are we sure that on the server side nobody has disabled the user so this 401 was generated somewhere .

Steps to reproduce

1. select a user
2. choice an option for delete / wipe / disable

Expected behavior

-1-
the duplicate of Delete user / Wipe all device should simply be "Delete user" I would like to remind you that at least under iOS, the data in the sandbox is and will remain unlawful, so even if you do not destroy the local data, it will remain unusable.

-2-
use a different error between delete and disable.

-3-
Deleting or disabling a user should generate an error that is not a 401 standad as it can happen in other contexts as well.

The report names no source files, tests, logs, or specific entry points. Start by reproducing the Delete user, Wipe all devices, and Disable user actions on Nextcloud Server 26, then compare the resulting client responses and local-data behavior. Done means the three operations have clearly defined, distinct behavior and verified client-facing errors.
