Resolve ENS human readable names

**Describe the solution you'd like**
Support for [ENS](https://ens.domains/) domain names.

**Describe alternatives you've considered**
ETH addresses will still be supported .

**Additional context**
See how it's done in [other wallets](https://ens.domains/) , and [MetaMask](https://metamask.io/) in particular since it offers both desktop and mobile wallets .

Start by tracing the existing Ethereum address handling in the Go wallet and compare the requested ENS resolution behavior with the linked ENS and MetaMask references. Done means ENS human-readable names resolve while existing ETH addresses remain supported; no file or test is named in the issue.
