Subject: [PATCH] web(d-web): V36 share-version crossing widget on embedded
 dashboard

Surfaces ratchet state at a glance from the existing /v36_status JSON
(VOTING/ACTIVATED, vote %, work-weighted signaling, current->target
share version) -- the same internal state debug.log uses, never a stub.

Charter #3 (crossing visibility): makes the live V35->V36 cross legible
to the operator directly in the dashboard, serving LTC prod #288.

Static drop-in to the on-disk --dashboard-dir; card defaults hidden and
renders only on a successful fetch, so it degrades gracefully on coins
or nodes where /v36_status is empty. Non-consensus web layer only.
