Refactor 'Token' types

[0xonramp]

Simplify Token usage across codebase so it's consistent

const hyeth = getTokenFromSymbol('hyETH')!
export const HighYieldETHIndex: Token = {
...hyeth,
coingeckoId: 'hyeth',
fees: {
streamingFee: ' 0.95%',
},
image: hyeth.logoURI,
indexTypes: [IndexType.leverage],
isDangerous: true,
url: 'hyeth',
}

Should use new tokenlist - once in production.
