Refactor handle_reclaims to avoid option wrap/unwrap

[HaoranYi]

Problem

Split from #7624

This PR refactors handle_reclaims function and its callers to eliminate option wrapper.

Summary of Changes

1. Simplified handle_reclaims Function Signature

• Changed the first parameter from Option to I directly
• Removed the conditional wrapper logic that was checking for Some(reclaims)
• Streamlined the function flow by removing unnecessary nesting

2. Updated Caller Sites

• Replaced (!reclaims.is_empty()).then(|| reclaims.iter()) pattern with direct reclaims.iter() calls
• Added explicit empty checks at call sites before invoking handle_reclaims.
• Early returns for empty reclaims to avoid unnecessary function calls

3. Remove a debug log.

This PR also is removing this debug log.

I think it's fine, but not something I was expecting to see based on the PR's title and description.

Good catch — I have updated the description to mention the removal of that debug log as well.
