Encryption: Update/clarify what admins can see

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).

Bug description

I have two server-side encrypted Nextcloud instances, one with master key and one with user keys.

The one with master key enabled says : "Your home storage is encrypted using server-side-encryption ↗ with a master key. It means that administrators can access your files, but not read their content."

If I'm not mistaken, that's not true as I'm able to decrypt files without any known user password with this setup.

Steps to reproduce

1. Enable server-side encryption with default module and settings (master key encryption)
2. As a user go to Personal Settings->Privacy
3. Read information about encryption

Expected behavior

The text should read something like this:

 "Your home storage is encrypted using server-side-encryption ↗ with a master key. It means that although your files are encrypted, system administrators can access your files and read their content."

Additional info

No response

The affected text appears under Personal Settings → Privacy in the privacy center; start by locating the encryption message in the repository. Update it to accurately explain that administrators with a master key can access and read users’ files, then verify the revised wording in that view.
