fix: resolve model paths for toolbox container access

Toolbox containers mount host / at /run/host/ but only /home is directly
accessible. Models on /data/models/ need the /run/host/ prefix when passed
to llama-bench inside the container.

Both run-baseline.sh and run-suite.sh now resolve model paths with realpath
and prepend /run/host/ for non-home paths. Paths under /home/ are passed
as-is (already mounted directly).

Verified with smoke test: Qwen3.5-0.8B-Q8_0 → 8900 t/s pp512, 177 t/s tg128.
