scrypted: drop frame_interval_ms, brightness default 80 → 100

Two settings cleanups now that streaming has landed:

- frame_interval_ms removed entirely. Under the TCP streaming data
  plane ffmpeg emits at the camera's native rate and TCP backpressure
  naturally caps us when the firmware can't keep up. The setting,
  the getter, the UI field, and the -vf "fps=N" filter argument all
  go away. Net: a few fewer questions to answer on every viewport,
  and one fewer place for the user to misconfigure latency. Existing
  storage values are silently ignored on next render.

- Default brightness 80 → 100. The panel is dim enough at 80 that
  the change in ambient lighting can wash it out; 100 is a better
  default. Users who want lower can still set it in the UI; this
  only affects newly-created viewports (existing ones keep whatever
  was last saved).
