v2.7.2: Aircraft list screen, radar night dimming, and flash savings

New:
- Aircraft list (Menu -> Flight Options, top entry): sortable list
  (distance/altitude/callsign) of every aircraft currently in range,
  with the same altitude color-coding and emergency/watchlist border
  highlighting as the radar. Tapping a row jumps back to the radar
  with that aircraft's detail panel already open.
- Night dimming now also softens the radar screen itself (aircraft
  markers and the sweep line switch to darker tones) during the
  existing 22:00-06:00 window, reusing the same setting - no new
  toggle.

Improved:
- Removed the unused built-in TFT_eSPI number fonts (GLCD/Font2/
  Font4/Font6/Font7/Font8) from platformio.ini - the project only
  ever uses the custom UI font via setFreeFont(). Saves ~15KB flash.

Also documents a CYD-flightradar.bin staleness safety check in the
CLAUDE.md release workflow (delete any leftover copy from a previous
release before renaming the fresh build, so an old binary can never
be silently re-used for a GitHub release).
