[Bug]: Files sharing expiration date is not displayed in profile locale format

⚠️ 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).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

The displayed date in file expiration menu is not using the profile defined (locale) date format.
In my case, the use profile is defined as the following with date in the format DD/MM/YYYY.

The expiration menu is using another format MM/DD/YYYY which create misunderstanding when you are typing the date directly.

Steps to reproduce

1. Define your profile locale to France and your language to British.
2. Go to the file app
3. Share a file and set an expiration date.

Expected behavior

The date format should be the one defined in profile locale. Otherwise, a warn note is welcome.

No response

No source file, test, or entry point is identified in the report. Reproduce the sharing expiration flow with a France locale and British language setting, then trace the date input and display formatting. Done means the expiration date follows the profile locale format or clearly warns when it does not.
