feat(new-chains): add q4 chains (#191)

# Description

Add Linea and Plasma by updating SDK to latest version.
It also required some minor adjustments to work with the new multi-pkg
sdk

# Changes

- [ ] Bump to cow-sdk 7.1.0
- [ ] Added global adapter for ethersv5
- [ ] Adjusted types as needed
- [ ] Added Linea config example

## How to test

- Unit tests
- Run the service locally with Linea config:

```json
{
  "networks": [
    {
      "name": "linea",
      "rpc": "https://rpc.linea.build",
      "deploymentBlock": 25028604,
      "filterPolicy": {
        "defaultAction": "ACCEPT",
        "conditionalOrderIds": {
          "0x5b3cdb6ffa3c95507cbfc459162609007865c2e87340312d3cd469c4ffbfae81": "DROP"
        },
        "transactions": {
          "0x33ef06af308d1e4f94dd61fa8df43fe52b67e8a485f4e4fff75235080e663bfa": "DROP"
        },
        "handlers": {
          "0xd3338f21c89745e46af56aeaf553cf96ba9bc66f": "DROP"
        },
        "owners": {
          "0xd3338f21c89745e46af56aeaf553cf96ba9bc66f": "DROP"
        }
      }
    }
  ]
}
```

* Should start as expected and sync to latest block
- Add a custom Safe app
https://swap-dev-git-feat-q4-chains-cowswap-dev.vercel.app/
- Place a TWAP order
* TWAP should be created
* Should see log entries in the console similar to:
