fix: transaction screens name a token from the tokens of the transaction's network (closes #629)

decodeCalldata() looked a token's symbol and decimals up in the active
network's tracked tokens and balances, whatever chain id it was given, so
TransactionDetail and TxApproval showed a token tracked on another network
by address only, with its amount in base units. The lookup now uses what the
wallet knows of the tokens on the transaction's network: the active
network's tracked tokens and balances, or for another network the tokens
tracked on it and no balances. TxApproval's token labels, the symbol it
hands the wait, success and error screens, and SuccessTx's decoded token
label use the same lookup.
