Phase: Pool API Modularization - Step 4: Extract pool_block_to_user_box.h

Browse Source 
Extract 30 lines: hak_pool_block_to_user() + hak_pool_block_to_user_legacy()
- New box: core/box/pool_block_to_user_box.h (helpers for block→user conversion)
- Updated: pool_api.inc.h (add include, remove extracted functions)
- Build: OK, bench_mid_large_mt_hakmem: 9.17M ops/s (baseline ~8M)
- Risk: MINIMAL (simple extraction, no dependencies)
