feat(hyperevm): register native and stablecoin contracts (#549)

Pre-stage the per-chain values HyperEVM needs once the network is added
to dbs-config (network id: hyperevm):

- WHYPE in the native-token registry
- USDC, USDT0, USDe, feUSD, USDH in the stablecoin registry
- hyperevm -> HYPE for NFT sale currency
- hyperevm chain id 999 in the spam-score map (commented, pending model)
