fix: increase health check timeout from 60s to 180s for slow HDD

The NAS HDD is slow enough that container startup can exceed 60
seconds. The app was starting successfully (Uvicorn running) but
the health check timed out just before the container became healthy.
Increased to 90 iterations at 2s = 180s max wait.
