feat: Store auction instances including liquidity

[fhenneke]

Problem

Since switching solvers to the new auction format, auction instances from the driver (including liquidity) are not stored anymore. Since those instances have been used for EBBO testing, some EBBO checks are currently not working.

Since we want to move forward with formalizing EBBO, having auctions instances is required to get a better overview of the magnitude of EBBO violations.

Suggested solution

Store auction instances from one of the solvers which receives liquidity, similarly to how it was done for the legacy format. Auction instances from the autopilot are not enought since they do not contain liquidity.

Here is a pointer to the code where this was done in the legacy solver implementation:

services/crates/solvers/src/infra/persistence.rs

Line 7 in dd2fe4b

impl Persistence {

The s3::Uploader is already a shared crate and should be reusable in the driver. We should allow a per solver configuration to upload (different solvers could use different paths on the bucket) but in practice only enable uploading for Quasimodo.
