Remove remaining debug logs from hot paths

Additional debug overhead found during perf profiling:
- hakmem_tiny.c:1798-1807: HAK_TINY_ALLOC_FAST_WRAPPER logs
- hak_alloc_api.inc.h:85,91: Phase 7 failure logs

Impact:
- Before: 2.0M ops/s (100K iterations, logs enabled)
- After: 8.67M ops/s (100K iterations, all logs disabled)
- Improvement: +333%

Remaining gap: Still 9.3x slower than System malloc (80.5M ops/s)
Further investigation needed with perf profiling.

Note: bench_random_mixed.c iteration logs also disabled locally
