TransactionDetail read the block, network details and calldata from the
active network's Blockscout and decoded the calldata for the active network,
so after a network switch a transaction sent on the other network showed none
of them. It now reads them from the Blockscout Settings has for the network
the transaction was sent on, and decodes the calldata for that network.
endpointsByChainId() in the shared view helpers gives a network's RPC and
Blockscout URLs, picked as reviewedNetworkProvider() picked its node;
reviewedNetworkProvider() now uses it. Restore refuses a stored transaction
whose chain id names no network, as it does for WaitTx.
