feat(settings): About logo scales to card height; Node&Security Advanced expander; lite gating

- About: draw the logo deferred, scaled to the card's full height (aspect-preserved,
  capped to the reserved width) so there's no empty space below it.
- Node & Security: split the daemon toolbar — Refresh + Test connection stay visible;
  the rare/destructive actions (Install bundled, Rescan, Delete blockchain, Repair
  wallet) move behind a collapsible "Advanced" header (reusing the DEBUG LOGGING idiom).
- Lite gating: hide the DEBUG LOGGING card (dragonxd debug= categories, no daemon in
  lite) and the RPC-backed encrypt/change/lock/remove block (lite has its own encryption
  in the NODE column) behind full-node guards; label the lite left column "WALLET" not
  "NODE". (Auto-lock + PIN remain in both.)
