Same defect and same fix as the user list's actions cell (#177):
display:flex directly on the override td removed its table-cell
behaviour, so the cell stopped growing to row height and its bottom
border no longer met the row's — visibly uneven separator lines
(Stefan's screenshot from the self-hosting walkthrough). The flex
layout now lives on .quota-row__override-inner.
Measured locally like #177: bottom-delta across all cells of every
quota row was 24–49 px before, 0 px after (override set, so the cell
carries input + two link buttons); admin-quotas e2e pack green.
