[feat](trx-frontend-http): add satellite scheduler UI in web frontend

Add HTML, JS, and CSS for the satellite pass scheduling overlay in the
scheduler settings panel.  The satellite section is always visible
regardless of the base scheduler mode (Grayline/TimeSpan) since it
operates as a preemption overlay.

UI features:
- Enable/disable toggle for satellite pass preemption
- Configurable pre-tune seconds (time before AOS to start tuning)
- Satellite entry table with add/edit/remove (satellite name, NORAD ID,
  bookmark, min elevation, priority)
- Preset dropdown for common weather satellites (NOAA 15/18/19,
  Meteor-M2 3/4) that auto-fills name and NORAD ID
- Bookmark selector for each satellite (sets freq, mode, decoders)
- Live pass status badge showing active satellite from scheduler status
- Status card shows "[SAT: name]" label when satellite pass triggers
- Scheduler control row visible when satellites enabled (even with
  base mode disabled)
