Introduces shared seams for paginated views, D-pad reorder, media control routing, async singletons and the device method channel, then points the open-coded copies at them. Also removes unused models and duplicated provider/server plumbing, folds the twice-implemented artifact store in the server, and factors the repeated Flutter toolchain prologue in CI into a composite action.
