fix: lo.Reduce in Command.LogValues discards accumulator

[abhinavdahiya]

Fixes #2888

Description

The lo.Reduce call in LogValues() was ignoring the accumulator parameter, so it returned only the last candidate's reschedulable pod count instead of the sum across all candidates. This caused the "pod-count" field in structured disruption logs to under-report during multi-node consolidation.

How was this change tested?

Added TestLogValues_PodCount that creates a Command with two candidates (3 and 2 reschedulable pods) and verifies the pod count is the sum (5), not the last candidate's count (2). Full disruption test suite passes (232/232).

Hi @abhinavdahiya. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
