fix(webui): keep modern station-card Delete action aligned on the footer row (#2083)

The modern station-card footer laid the 5 action buttons in a non-wrapping
inline-flex group beside the Delete button, inside a wrapping footer. Once the
group's max-content width exceeded the card, the footer broke the line between
the group and Delete, dropping Delete onto its own row where margin-left:auto
pinned it bottom-right (orphaned) instead of aligned with the other actions.

Make the footer a single flex line (flex-wrap: nowrap) and let the action
group wrap its buttons internally (flex-wrap: wrap) so it reflows across rows
on narrow cards while Delete stays on the same row, pinned right. align-self:
flex-start top-aligns Delete with the first action row when the group wraps.

Presentational modern-skin CSS only; no markup or handler change.
