Slots list is clipped when the console is docked

Seen during task 7370's visual check, at 1280 px on /worktrees (Automation › Slots) with the Web Console docked on the right: - The slots table is cut off on the left: its summary reads "uilt yet · on 3 nodes", and the identity/project column is hidden, so the rows show only the node, which every row shares. Keep the slot identity column visible, or let the table scroll horizontally inside its card. - With the identity hidden, every row reads "dev-node — ? ? — None", so the operator can't tell which slot a row is. Truncate the node column before the identity. - The console header showed "free" for a slot whose console runs a task. Check that the header title follows the slot's state. Out of scope: the console body and the Chat/Terminal switch. Done means: a screenshot at 1280 px with the console docked shows each row's slot identity (e.g. `cto#1`) and an untruncated summary line.

Slots pool now drops columns by its own width (node first), and flat rows show cto#1 when the Project column drops; the console header no longer says "free" for a task-held slot. Quick gate and e2e green; visual check at 1280px with the console docked shows the identity and the full summary. PR #6052 merged; deploy superseded. Follow-up draft #7508.
