fix(question): show both language fields for MCQ options

Options editor used a single toggle-based bilingual field (BilingualInput)
that swapped English/Amharic in place via a tiny, easy-to-miss button.
Authors were filling English only and never noticing Amharic was empty.

- QuestionOptionsEditor: show separate always-visible English/Amharic
  TextInputs per option instead of the toggle field.
- BilingualInput (shared): for other callers still using the toggle,
  add a tooltip and a red dot indicator when the hidden language is
  empty, so the gap is visible without switching.
