Datatypesettings infinite overlay view: Add fallback texts and map label to input id

[BatJan]

Prerequisites

• I have added steps to test this contribution in the description below

Description

In this PR I have added a new translation key, which was missing for part of the text and I have mapped missing fallback texts ensuring a text will be displayed in case other language files are out of sync.

Furthermore I have ensured that the name label, refers the associated input as well improving accessibility a wee bit.
