refactor(logo): HanzoLogoIcon consumes @hanzo/logo (single source)

Stop re-typing the block-H path data — import MARK_PATHS/MARK_VIEWBOX from
@hanzo/logo (the one geometry home). Byte-identical mark, same props
(className/size/currentColor), 4 consumers unaffected. Needs @hanzo/logo
published install to update the pnpm lock (deploy-gate); scoped tsc of the
changed file green against real react + logo types.
