fix: add DAYTONA_OVERRIDE_STORAGE passthrough to cap disk at 10GB for Daytona

Daytona sandboxes are limited to 10GB storage per sandbox. Tasks with
storage = "20G" or storage_mb = 20480 in task.toml fail immediately.
Set DAYTONA_OVERRIDE_STORAGE=10240 alongside HARBOR_ENV=daytona to cap
all sandbox disk requests at the Daytona limit.
