context-menu: add Copy text action and always show Mark done

- New "Copy text" entry next to "Save .md": copies title + blank line +
  body to the clipboard, with fenced code blocks (incl. slide-image),
  markdown images / links / formatting, and inline #tags stripped.
- "Mark done" is now visible on every card (used to require a due_date
  to even show up). On a card already tagged #done it flips to "Unmark
  done" and removes the tag. The original due-date-clearing behavior is
  preserved when transitioning a due card to done.
