Replace the hardcoded demo DEX dataset (incl. the placeholder pi-million 24h volume) with live markets + fills from the C-Chain 0x9999 subgraph at the per-network /v1/graph/cchain/dex/graphql endpoint, selected via config.apis.general like every other resource. Token pairs resolve through the existing token metadata endpoint, falling back to a short address. Empty/unavailable nets render 'No active markets' — never mock.
Guard tx.transaction_types in TxsListItem so coinbase/precompile txs (absent transaction_types in the API payload) no longer crash the block Transactions tab; drop an unused destructured prop. Allow CLOB in cspell.
