fix(order-ticket): drop catalog-price fallback when orderbook will load

The sell-side proceeds preview flickered: catalog market.price (often
stale or off by an order of magnitude on thin venues like Limitless)
rendered instantly, then ~100ms later the live bid landed and the
proceeds jumped. Use the live book only when a tokenId is present;
fall back to market.price only for UUID-only picks where no book
fetch is possible.

Bumps widgets to 0.5.9.
