fix: return reward delta instead of validator balance as sync committee rewards

[nflaig]

Closes #8718

[gemini-code-assist]

Summary of Changes

Hello @nflaig, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the computeSyncCommitteeRewards function to provide a more accurate representation of sync committee compensation. Instead of returning a final balance for validators, which previously included a penalty floor, the function now directly computes and returns the net reward or penalty delta. This change ensures that the output precisely reflects the reward earned or lost by validators for their participation.

Highlights

• Reward Calculation Logic Change: The computeSyncCommitteeRewards function now calculates and returns the direct reward delta for each validator in the sync committee, rather than a modified balance that included a floor of zero.
• Removal of Balance Capping: The previous mechanism that capped penalties to prevent a validator's balance from dropping below zero has been removed, aligning with the new focus on reporting the raw reward/penalty delta.
• Data Structure Refactoring: The BalanceRecord type and the balances Map have been replaced by a rewardDeltas Map, which directly stores the numerical change in rewards for each validator.

Code Review

This pull request effectively addresses a critical bug in computeSyncCommitteeRewards. The changes correctly modify the function to return reward deltas instead of the full validator balance, aligning it with its intended purpose. Additionally, it fixes a significant issue in how sync committee participants were being iterated, preventing potential out-of-bounds errors by using the correct position index. The updated logic is much clearer and more correct. I've added one minor suggestion to further improve code conciseness.
