Character limit for text

Text fields need character limit, otherwise the components can stretch beyond the screen 👎

The issue does not name files or tests. Start by locating the React text-field components responsible for sizing and input behavior, then identify how their current dimensions are determined. Done means text fields enforce a character limit or equivalent bound so components do not stretch beyond the screen; add or run the relevant UI tests if they exist.
