[TRIVIAL] Fixed driver OpenAPI /reveal request definition

[mstrug]

Description

OpenAPI driver /reveal request has 3 fields: solutionId, submissionDeadlineLatestBlock, auctionId which is inconsistent with the source code, where /reveal request has only 2 fields: solutionId and auctionId: source.

Changes

/settle and /reveal endpoints have same API definition: Solution, so I've created new API component: SolutionWithDeadline and assigned it to /settle endpoint. From Solution I've removed submissionDeadlineLatestBlock field which now aligns with /reveal endpoint source code.
Renamed driver settle dto module solution.rs to solution_with_deadline.rs and name of the struct Solution to SolutionWithDeadline.

Reminder: Please consider backward compatibility when modifying the API specification.
If breaking changes are unavoidable, ensure:

• You explicitly pointed out breaking changes.
• You communicate the changes to affected teams.
• You provide proper versioning and migration mechanisms.
