Build 18: move the integrated node off the wallet list into the cog

- Remove the Node status chip from the wallet-list header; the integrated
  node now lives in the cog's settings as a status + Enable/Autorun section,
  with a "Node settings" button into the full stats/mining/tuning panel.
- Stop the desktop two-column rail from auto-docking the node beside the
  settings screen, so the node has a single home in the cog at every width
  (the full panel opens only on demand). Fixes the wide-window double-exposure.
- Prove NIP-17 payments transit the top public relays: parameterize the
  nostr e2e roundtrip and add damus.io + nos.lol proofs (3/3 green).
- Add DEVELOPING.md documenting how we iterate and test (Xwayland :2 recipe,
  Build N cadence, gui-sweep, e2e tests, live infra) — no secrets.

Verified live on :2: chip gone from the list; cog shows the node once
(single column, no left rail); "Node settings" opens the full panel on
demand. 34 lib tests green; nip17 roundtrip green over nrelay + damus + nos.lol.
