v2.5.0: History chart, web export, and marquee fix for nearest airport

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. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
