[LOW] Wrong SS58 prefix used in vault log

[timbrinded]

Description

The vault logs uses prefix 42 instead of whichever chain it is connected to e.g. 2092 for kintsugi.

Tested against: kintsugi main net, vault is successfully integrated to the network though, so this is logging defect only.

Steps to recreate

1. Run setup for kintsugi mode and start vault as normal

⚠️ Account format used is not for kintsugi
