Adds FlightLogbook::todayMaxAltitude(), which scans today's logbook
CSV for the entry with the greatest altitude at first sighting, and
displays it as "Highest flight today: <callsign> (<alt> ft)" on the
Statistics screen (Menu -> Flight Options -> Statistics).
Also documents the CYD-flightradar.bin rename step (for GitHub
release uploads) in the CLAUDE.md release workflow.

Adds a 7-day bar-chart view of the flight logbook (Menu -> Flight
Options -> History chart), and a small built-in web server that
serves a logbook overview page plus a merged CSV export of all
logged days once the device is connected to WiFi (discoverable via
the "?" button on the Logbook files screen, which now also shows the
live device IP). Also fixes the "nearest airport" line on the
Location Presets screen, which previously used tft.setViewport() and
went completely invisible with our custom font - it now scrolls as a
proper marquee without relying on the viewport clip.
Also documents the standard release workflow in CLAUDE.md.
