fix: WaitTx and TransactionDetail use the network the transaction was sent on (closes #584)

WaitTx asked the active network's node for the receipt, so after a network
switch a transaction sent on the other network was never found and was
reported as timed out. It now asks the node of the network its chain id
names, through reviewedNetworkProvider(), moved from ConfirmTx into the
shared view helpers so both screens use one function. WaitTx and
TransactionDetail build their explorer links for that network too. A stored
wait or transaction whose chain id names no network is refused on restore,
as a stored ConfirmTx transaction already is.
