feat(toast): message toast opens the related chat + has a close icon (#33)

- Add a close (X) button to the message toast (closeToast, @click.stop) like the
  system notifications.
- Carry the sender pubkey on the toast; clicking now deep-links to that
  conversation (/dashboard/mesh?peer=<pubkey>) instead of the generic mesh page.
- Mesh.vue reads ?peer= on mount and opens the matching peer (by pubkey_hex/did),
  gracefully falling back to the mesh list when no match (B1/B2 identity).

type-check clean; useMessageToast tests 11/11.
