fix: column_text Typ fuer Sub-Sessions in Korrektur-Tabelle

_cells_to_vocab_entries kannte column_text nicht, daher wurden
keine Eintraege erzeugt. Jetzt mappt column_text -> 'text' Feld.

Frontend: column_text in FIELD_LABELS/COL_TYPE_TO_FIELD/COL_TYPE_COLOR.
Label: "Tabelle" statt "Vokabeltabelle" fuer Sub-Sessions.
