[4.0] Correcting wrong debug lang untranslated strings

[infograf768]

Summary of Changes

Adding some missing labels (filter_contacts, filter_articles), correcting a typo (filter_banners), prevent double translation for tooltip (transition-button);

Note: I could not find why COM_NEWSFEEDS_CATEGORIES is noted as untranslated as the sys.ini is loaded...

Testing Instructions

Make sure #27074 is merged or merge it first.

Set debug lang on, show its subpage and navigate in the managers concerned above
Look at the Untranslated strings.

The menutypes are noted as Untranslated but this is expected (see explanation here: #27068 (comment) )

Actions is marked as double translated, but we already have an issue for that and we were not able to find a solution.

Before patch

Example when the Articles Manager is displayed

After patch

Documentation Changes Required

Look at the other filters where the format is - Select XXXXX -. This is only Featured.
