Subject: [PATCH] fix: remove FEI and RENBTC from Ethereum default tokens

FEI: Fei Protocol officially dissolved in August 2022 (Tribe DAO
voted to redeem FEI->DAI and wind down operations). Observed in
production: CoinGecko price for this token gets stuck/fails to
refresh for 25+ minutes at a stretch while every other configured
token refreshes normally each cycle.

RENBTC: the backing bridge (RenVM) shut down in late 2022 following
the Alameda/FTX collapse, with no active development since.
On-chain volume is negligible (~$3/24h as observed), making it
unsuitable as a fee token even though it still resolves a price.

Neither token is a good candidate for fee collection: FEI is a
defunct stablecoin and RENBTC is functionally illiquid.
