feat(supervise): show the bottle's human slug, not its opaque id

Consolidated proposals are keyed by the orchestrator-assigned bottle_id,
so the supervise TUI was rendering a hex id (e.g. 3601cbe883c2786d) as
the bottle name — and the resume hint printed `./cli.py resume <id>`,
which resume can't take (it wants the human identity/slug).

`supervise_pending` now tags each dict with `bottle_label` — the human
slug resolved from registry metadata, falling back to the id when the
bottle is gone. `QueuedProposal` carries the label; every display site
(list rows, detail view, status lines, resume hint) shows it, while
approve/reject still key on `proposal.bottle_slug` (the id).
