fix: always name a swap's output token, by address when no symbol is known (closes #346)

The Token Out line was pushed only when a symbol was known, so a swap to a token absent from the bundled list showed a Min. received figure with no statement of which token was being received. It now falls back to the address, mirroring the Token In precedent in the same file. Composes with the unknown-scale refusal from #340: the address names the token while the figure declares its scale unknown. Native ETH out, ETH out via UNWRAP_WETH and bundled tokens render exactly as before.
