refactor: single source chainId type

[TravellerOnTheRun]

Not that we have ChainID type from EOAWallet we can use it. @jormelCoin make sure nothing breaks after this PR.

When I load this up and try to recover via a mnemonic it doesn't create the wallet, rather it deletes some of the inputs and restarts. I checked that the develop branch is working correctly.

See video of this branch:

Please, check again, getWalletSetting was used the old way, I believe I've changed it in my EOA PR maybe someone committed those changes back accidentally we need to watch closely what's committed.
