refactor(dashboard): head the card with the session name, move the worktree beside the project

The conversation name now sits next to the agent icon as the card's heading
rather than prefixing the user-message line, and the worktree drops to the
footer beside the project icon. The message line reads "You" again — the name
moved up, so keeping it there said the same thing twice.

Cards without a resolvable session name keep the worktree as the heading, and
the footer omits it rather than repeating it.
