forgepulse: the rank column stops stretching to the row height

The rank-trend arrows in forgepulse’s Repository signal table cost every row its bottom border alignment: display: flex on .rank-share, added to stack the arrow, pulled that <td> out of table layout, so it stopped growing to the row’s real height and stayed clipped to its own content while the Name column stretched normally for longer descriptions. Dropping the flex display and keeping the existing block-span stacking restores the alignment — two lines of CSS, which is what a change made to fit a two-character indicator should have cost in the first place.
