chore: Extend `/quote` response with pre-interactions and Jit orders

Background

Currently CoW Protocol is in an awkward spot because it can not be the only source of liquidity yet. If all liquidity for a token rests in CoW Protocol's orderbook or some CoW AMM solvers would have no way of using it to quote a price for a given token.

Details

To fix that we should allow solvers to return pre-interactions and JIT orders with their quote. That way solvers could quote with CoW AMMs (require JIT orders and pre-interactions). They could also index the orderbook and return resting limit orders as JIT orders.

Acceptance criteria

update driver -> autopilot /quote reponse to pass a list of pre-interactions and a list of JIT orders (format of jit orders should ideally be the same as in the /solve endpoint)
updated the openapi spec
