The same issue as cross checkpoint caching, see details in WT-18168.

Proposed fix

On put path, we should check if a page is named checkpoint via WT_DHANDLE_IS_CHECKPOINT((btree)->dhandle).

On read path, we need to check the same, and add a flag like WT_PAGE_LOG_CACHE_BYPASS in the read request so block cache can be aware of that and consider that as a miss.

We need to add a test case to validate this is true before proceeding, and also to verify the fix is working.
