Moe Charm (CI) 0752688785 Phase REFACTOR-2: Legacy Fallback Logic Unification

Consolidate duplicated legacy free logic into a single reusable function.
Previously, hak_tiny_free_legacy_inline() and hak_tiny_free_legacy_impl()
contained identical implementations in malloc_tiny_fast.h and
tiny_c6_ultra_free_box.c.

Changes:
- NEW: core/box/tiny_legacy_fallback_box.h
  - tiny_legacy_fallback_free_base(): Unified legacy free implementation
  - Encapsulates: Unified Cache push + per-class stats + final fallback
  - Contract: BASE pointer input (already extracted from USER ptr)

- Modified: core/front/malloc_tiny_fast.h
  - Removed: hak_tiny_free_legacy_inline() (lines 96-111)
  - Replaced call: hak_tiny_free_legacy_inline → tiny_legacy_fallback_free_base

- Modified: core/box/tiny_c6_ultra_free_box.c
  - Removed: hak_tiny_free_legacy_impl() (lines 17-39)
  - Replaced call: hak_tiny_free_legacy_impl → tiny_legacy_fallback_free_base

Benefits:
- Single source of truth (DRY principle)
- Easier to maintain and test
- Consistent behavior across all free paths
- No performance impact (always_inline preserved)

No semantic changes - identical logic, just centralized.
