Record each forecast change (Zambretti letter transition) with a timestamp into a 24-entry ring buffer, persisted to LittleFS and restored on boot. New /api/forecasts endpoint and a 'Forecast log' panel in the web UI (newest first, category colour, timestamp). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
