Fixed loot materialization

- Container loot finishes on its owning thread before pending markers clear
- Failed fills restore container contents and deferred native loot state
- Failed materialization remains pending without refilling completed containers
- Vanilla tables resolve from the current registry after reload
- Studio loot previews follow the player scheduler
- Tests cover loot rollback, retries, cancellation, and container classification
