Round-2 review polish on PR #885:
- Document in the deck_move_card_to_board tool that the move reassigns the
card owner to the calling user and resets the done timestamp (both are
limitations of Deck's move route), so an LLM reading only the tool
description isn't misled about preserved fields.
- Fix the done integration-test docstring to say "done state (not timestamp)".
- Add test_move_card_to_board_preserves_archived_status to lock in the
documented archived-preservation behaviour.
