chore(deps): take @conduction/nextcloud-vue 2.25.1 for the KPI card

2.25.x makes the canonical KPI card flat and horizontal, so dashboards stop
drawing a grey box inside the white card CnWidgetWrapper already draws, and
2.25.1 fixes the narrow-tile step-down that 2.25.0 shipped inert (a source-order
bug left KPI values clipped on a three-column tile).

The caret range already allowed both; only the lockfile pinned this app back.
Lockfile only.
