fix(exam,result): collapse row actions into a dropdown menu everywhere

Same treatment as the questions table, applied consistently: exams list,
exam results list, and the exam-detail candidates panel all now show a
single Actions button opening a dropdown instead of a row of inline
buttons/icons. Also fixes the exams list's action column header, which was
rendering the literal untranslated key ('exam.columns.actions') — missing
a fallback string, same pattern already used elsewhere in this file.
