Some column headers in the Angular staff client appear untranslated

[Eva Cerninakova]

Some interface labels and column labels  are displayed untranslated in various Angular interfaces (in Evergreen 2.6.2). It concerns e.g. Acquisition interfaces or various setting interfaces in Locale Administration or Server Administration - se the attachment.
I am not sure where the strings come from. Just for completeness: I randomly tried to look for several of them in Poeditor, but to no success.

Also the labels in all settings editors are displayed untranslated, see the attachment.

The issue is still relevant in Evergreen 3.9 - the column labels of the newly angularized interfaces are not translatable (the strings are not available in POEditor for translation)
