* feat: add trading offers section for taproot assets
Query liquidity offers from an external API showing lightning nodes
that provide exchange between taproot assets and bitcoin. Each node
advertises their own exchange rate.
- Add TRADE_API_URL env var for configurable API endpoint
- Server proxies external GraphQL API via FetchService (same pattern as Amboss)
- Trading tab with asset selector, buy/sell toggle, sortable offers list
- Each offer shows node alias/pubkey, exchange rate, available amount

* chore: add small copy
* feat: add node capabilities query and disable tapd nav when unavailable
Add getNodeCapabilities GraphQL query that exposes provider capabilities.

Also show a message when user has no supported assets to sell.
