chore: bump sor to 4.7.0 - feat: SOR level implementation to support 1) expanding mixed quoter v1 to L2s 2) support migrate mixed quoter v1 to mixed quoter v2 across chains

[jsy1218]

this PR compliments Uniswap/smart-order-router#746, and will be able to achieve:

1. routing-api to shadow sample mixed routing against mixed quoter v1 across L2s. There's no accuracy to compare, just make sure routing-api shadow mixed routing success rate is high - existing metrics in routing-api ON_CHAIN_QUOTE_PROVIDER_${this.EXACT_IN_METRIC}TRAFFIC_TARGET_FAILED_CHAIN_ID${this.chainId}

On L2, only Base has the MixedRouteQuoterV1 deployed (see context). I thought its due to the lack of FOT and exact out support. But its actually due to SOR only enables mixed routing on L1 https://github.com/Uniswap/smart-order-router/blob/66927c4e4f7e75138df48afab1c33a6c6d8d8f15/src/routers/alpha-router/alpha-router.ts#L2081.

Therefore in this PR, I will only enable shadow sampling against Base mixed routing on L2, but keep 100% mixed routing traffic on L1.

I also enhanced existing unit test coverages.

tests all passed on my local https://app.warp.dev/block/afa5Lrn5JUeIIscuDGm14B

Tested on my personal AWS account:

• L1 mainnet - I can see only V3 and Mixed, all hitting target quoter address. Because V3 is migrated from revert quoter to view-only quoter on L1, and MixedRouteQuoterV1 is live on L1. V4 is not deployed to L1.

• Optimism - I can see only V3 hitting targer quoter address. V4 and MixedRouteQuoterV1 is not deployed to Optimism.

• Arb - I can see only V3 hitting targer quoter address. V4 and MixedRouteQuoterV1 is not deployed to Arb.

• Polygon - I can see only V3 hitting targer quoter address. V4 and MixedRouteQuoterV1 is not deployed to Polygon.

• Celo - I can see only V3 hitting targer quoter address. V4 and MixedRouteQuoterV1 is not deployed to Celo.

• BNB - I can see only V3 hitting targer quoter address. V4 and MixedRouteQuoterV1 is not deployed to BNB.

• AVAX - I can see only V3 hitting targer quoter address. V4 and MixedRouteQuoterV1 is not deployed to AVAX.

• BASE - I can see only V3 hitting targer quoter address. V4 not deployed to BASE. MixedRouteQuoterV1 deployed, but sampling rate too low.
