Added CompactionOptionsFIFO::max_data_files_size to support FIFO compaction trimming based on combined SST and blob file sizes. Added CompactionOptionsFIFO::use_kv_ratio_compaction to enable a capacity-derived intra-L0 compaction strategy optimized for BlobDB workloads, producing uniform-sized compacted files for predictable FIFO trimming.
