[Bug]: Sharing files to public via emails should not be displayed in UI if it is turned off in settings

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.

Bug description

After the last update in v32 I've found that the files sharing UI contains the section 'External shares', explaining "Share files with others outside your organization via public links and email addresses. You can also share to {productName} accounts on other instances using their federated cloud ID."

At the same time in sharing settings the option "Allow users to share via link and emails" and Federation is off.

Steps to reproduce

1. Go to File sapp. Click Details
2. Go to section Share
3. Observe External shares

Expected behavior

This section should be hidden if "Allow users to share via link and emails" is off.

Additional info

No response

Start in the Files app's Details > Share view and trace how the “External shares” section is displayed alongside the “Allow users to share via link and emails” and Federation settings. Done when the section is hidden whenever the relevant sharing options are disabled, while remaining available when they are enabled; verify the reproduction steps on Nextcloud Server 32.
