Drop VIEWPORT_STATE_UNCONFIGURED — state is just awake/asleep

\`state\` now reports only the screen's runtime state (awake or asleep).
Whether a viewport is set up to talk to Scrypted is a separate
\`configured\` flag, derived from \`viewport_name && scrypted_url\`.
There's no third state.

Behaviour changes:
- POST /state always succeeds; the previous 409 "device unconfigured"
  path is gone. The screen toggles regardless of /config status.
- POST /config now sets \`configured\` directly from the derived
  predicate instead of mutating the state enum.
- Outbound state-client POST to Scrypted is still gated on a scrypted
  URL being present — that's the only thing the configured flag now
  actually controls in the runtime path.

GET /state JSON unchanged in shape, but \`state\` is now never
"unconfigured" — that's reported through the existing \`configured\`
boolean instead.
