feat(cashmere): add NEAR Intents support and all frontend chains (#457)
- Add NEAR Intents stablecoin domain IDs (500_XXX) - Add NEAR Intents native asset domain IDs (600_XXX) - Add LayerZero USDT0 chains (berachain, ink, corn, flare, rootstock, xlayer, plasma, monad) - Update token address mappings for all supported chains - Add isUSDVolume flag for USD-based volume tracking - Remove gnosis (not enabled on frontend) Co-authored-by: Cashmere Labs <[email protected]>
