Register each bucket when it is selected as a new bucket. Previously, later buckets received count entries before registration, leaving only the first bucket eligible for overflow assignment. Add regression coverage for complete, duplicate-free candidates and stable existing hash mappings. Signed-off-by: QuakeWang <wangfuzheng0814@foxmail.com>

Purpose
Follow-up on #7363. Newly allocated buckets received count entries before candidate registration, causing registration to be skipped. Once the bucket limit was reached, only the first bucket remained eligible for random assignment.
Register each bucket when it is allocated, keeping candidates complete and duplicate-free while preserving the random selection strategy and existing hash mappings.
