refactor(map): drop the 7-day outlook strip, fix missing Analysis, trim timeline
- Remove the 7-day outlook strip and daily_outlook_at/3. It was
  derived from point_forecast, which is capped at HRRR's 18-hour
  horizon, so it never had 7 days of data to show.
- factors_for: fall back to the nearest persisted analysis profile
  at or before the requested time. Only f00 hours persist profiles,
  so clicking any other hour used to yield an empty Analysis and
  factor table. After the recent cursor fix lands 'Now' on a
  forecast hour more often, this regressed further.
- available_valid_times/1: cap the forward horizon to 18h from now.
  Leftover valid_times from prior cycles used to pile on the
  timeline without adding information.
