feat: update both optimistic submission methods to use adjustment data v3

[yeguclu]

📝 Summary

Unify optimistic v1 and v3 submissions to use BidAdjustmentDataV3 format, removing BidAdjustmentDataV1 and intermediate conversion methods.

💡 Motivation and Context

Previously, v1 submissions used BidAdjustmentDataV1 while v3 submissions used BidAdjustmentDataV2. BidAdjustmentDatav3 format includes placeholder_gas_used, which relaxes the gas_limit == gas_used requirement for payout transactions. This allows relays to use the actual gas consumed, preventing adjustment failures when gas_used differs from gas_limit.

In addition to optimistic v3 submissions, since there already is a support for using the BidAdjustmentDataV3 with v1 submissions, we can simplify the codebase by:

• Removing BidAdjustmentDataV1 entirely
• Removing the intermediate BidAdjustmentData struct and conversion methods
• Using BidAdjustmentDataV3 directly for all optimistic submissions (both v1 and v3)
• Updating rest of the codebase to use BidAdjustmentDataV3
