Bad error handling for quotes

[anxolin]

Description

I can see we have an issue with our quoting 😅
We do 2 quotes, FAST and VERIFIED.
FAST returns:

{
  "errorType": "QuoteNotVerified",
  "description": "No quote for this trade could be verified to be accurate. Orders for this trade will likely not be executed."
}

Which I don't understand, as fast should not need verified quotes.
VERIFIED work, which is odd if fast fails!

{
  "sellToken": "0xfff9976782d46cc05630d1f6ebab18b2324d6b14",
  "buyToken": "0xbe72e441bf55620febc26715db68d3494213d8cb",
  "from": "0x54400BF44b7c5B3a8b70c958786ADFD74f1219Db",
  "receiver": "0x54400BF44b7c5B3a8b70c958786ADFD74f1219Db",
  "appData": "{\"appCode\":\"CoW Swap-SafeApp\",\"environment\":\"pr\",\"metadata\":{\"orderClass\":{\"orderClass\":\"market\"},\"quote\":{\"slippageBips\":50}},\"version\":\"1.1.0\"}",
  "appDataHash": "0x8d14d6e013f23bc66da0eb5714bbc0ad409f0c0cdc7e94d2986a8925a6ac90c3",
  "partiallyFillable": false,
  "priceQuality": "verified",
  "validFor": 1800,
  "kind": "sell",
  "sellAmountBeforeFee": "1000000000000000000"
}

The real issue to fix

But the biggest issue I see is, in the frontend, we handle badly this error and we don't let the user continue. So this is very problematic.

How to Reproduce

• Make the FAST quote to fail, and the VERIFIED to succeed.
• The button is disabled
