scrypted: name viewports from discovery; editable name on settings page

Creating a viewport with the name field blank fell back to "viewport"
with no way to change it afterward — display_name is deliberately the
canonical name (v.name drifts on reload), so the Scrypted device-name
pencil never propagated. Two fixes:

- createDevice: an empty name now inherits the discovered device's
  advertised TXT name, so picking "10.0.13.83 — kitchen (…)" from the
  host dropdown names the viewport "kitchen" without retyping.
- child settings gain a "Viewport name" field: updates display_name,
  mirrors the name onto the Scrypted device record, and re-registers so
  the firmware name + mDNS hostname follow.
