fix: add reverse ENS lookups for all displayed addresses (closes #22)

Previously, ENS reverse lookups were only performed for the single
counterparty address (from or to depending on direction). This meant
contract interaction targets and the non-counterparty side of
transactions never got ENS names resolved.

Now both from and to addresses are collected for ENS resolution,
ensuring all displayed addresses show their ENS names when available.
