feat(webapp): refresh the Usage page billing panels

Presentation-only redesign of the org Usage page: wrap the Credits and
Month-to-date panels in cards with a baseline-aligned value + title row and
a full-width bar, add a Set/Update billing limit link, match the two bars'
styling, drop the bar load animation, and tidy the Tasks header and empty
state. No loader/logic changes.
