Official vendor logos on store cards

Packages that talk to an outside service — an AI provider, a hosted API — can now display that service's real logo on their store card, in its own colors, exactly as the vendor publishes it. Until now every icon was repainted white and dropped onto a colored tile, which kept house icons readable but altered logos in ways their owners' brand guidelines do not permit.

An icon opts in by marking itself as an official logo. It then keeps its own colors and sits on a plain white tile, so it stays legible on both the light and the dark theme without being recolored.

The browser tab is deliberately left alone: a page whose node carries an official vendor logo still shows the MeshWeaver mark in the tab strip. A favicon says whose site you are on, not which service the page happens to talk to.
