Map TWAP (createWithContext call) orders

[iamacook]

Summary

We currently display TWAP (createWithContext) calls as a "standard" transaction and do not decode the data as we do with swaps. This implements TWAP-specific decoding behind a feature flag.

Official TWAP-based orders are now decoded and the txInfo is mapped as follows:

type TwapOrderInfo = {
  type: 'TwapOrder'
  orderStatus: OrderStatus;
  kind: 'sell';
  class: 'limit';
  validUntil: number;
  sellAmount: string;
  buyAmount: string;
  executedSellAmount: string;
  executedBuyAmount: string;
  sellToken: {
      address: `0x${string}`,
      decimals: number,
      logoUri: string,
      name: string,
      symbol: string,
      trusted: boolean,
  };
  buyToken: {
      address: `0x${string}`,
      decimals: number,
      logoUri: string,
      name: string,
      symbol: string,
      trusted: boolean,
  };
  receiver: `0x${string}`;
  owner: `0x${string}`;
  numberOfParts: number;
  partSellAmount: string;
  minPartLimit: string;
  timeBetweenParts: string;
  durationOfPart:
    | { durationType: 'AUTO' }
    | { durationType: 'LIMIT_DURATION'; duration: number };
  startTime: 
    | { startType: 'AT_MINING_TIME }
    | { startType: 'AT_EPOCH'; epoch: number };
}

Changes

• Add features.twapsDecoding feature flag
• Extract re-used values from Order entity to relative enums
• Add TwapOrderInfo entity
• Add TransactionInfoType.TwapOrder type
• Add test-covered GPv2OrderHelper for decoding order UIDs (based on CoW Protocol/SDK - linked in code)
• Add test-covered TwapOrderHelper for finding/generating parts of TWAP orders (based on CoW Swap app - linked in code)
• Add test-covered TwapOrderMapper for mapping TWAP orders
