Confirm function for text fields

[jancborchardt]

Lots of text fields in Nextcloud don’t have any immediately obvious way of what needs to be done next.

Some examples are:

• New -> text file / folder (you need to press enter)
• Password field in the share dialog and in the user management
• Sharing dialog user input field
• …

For each of these fields, we should have a small arrow button (class="icon-confirm") as a confirm mechanism on the right inside the field. Similar to the password reset mechanism, Add to Nextcloud text field in sharing, and the comment field in the right sidebar. It should not be a separate button, but integrated in the input field.

This is now done in most fields. When it still occurs, open separate issues for where it still needs to be fixed. :)
