dsh-remote 0.6.0: other machines' workspaces in the Workspaces list, richer Devices tab

- sidebar: workspaces (+ sessions) of every other device appear inside the stock
  Workspaces list with a server icon and the device name; click folds sessions,
  hover + creates a session there, a session opens as the remote conversation view
  (/r/<device>/#/session/<id>); the viewed device's own rows stay native
- Devices tab: every device with its state (online/offline, last seen, platform,
  workspace/session/running counts), offline and revoked devices included
- deploy/e2e-dom.mjs, e2e-eval.mjs: DOM dump / evaluate-in-page helpers
