Show the question bank as a table with a stable, right-aligned actions column

The old list showed type, text, and points inline via flexbox, with no
correct-answer info at all, and unstyled buttons that shifted position
depending on question text length. A table with a shrink-to-fit
actions column (text/kind/answer/points first, buttons last) fixes
both: correct answers are now visible, and button position no longer
depends on text length.
