… cache size percent overflow (#63410) Problem Summary: When file cache LRU restore creates a block from dump metadata and later lazy loading finds the same hash/offset with a smaller real file size, reset_range only updated the LRU queue size and _cur_cache_size. The FileBlock range still kept the old restored size, so a later async clear or eviction subtracted the old block size and could underflow _cur_cache_size, producing huge size_percent values in need-evict-cache-in-advance logs. This change makes reset_range update the FileBlock range as the single place that keeps the FileBlock, LRU queue, _cur_cache_size, and TTL size accounting consistent. FileBlock::finalize now delegates the range shrink to reset_range instead of changing the range before calling it.
