Add station alerts, dashboard analytics, and settings improvements

Alerts (server): - Station temp high/low threshold alerts via push + ntfy - Freeze warning at ≤34°F (station reading) - Station wind gust threshold alert from real readings - Station offline alert when no data for >20 min (auto-clears on reconnect) Dashboard: - Trend arrows (▲/▼/–) on temp, humidity, dew, wind, pressure, UV, solar tiles comparing current vs 1h ago via new /api/station/trend endpoint - Offline banner when station last reported >15 min ago - Monthly summary table (avg temp, high temp, max gust, total rain, readings) - Temperature calendar heatmap — GitHub-style year grid, blue→orange scale - Alert threshold settings UI: temp high/low, wind gust, rain rate saved to all push subscriptions via new /api/subscriptions/thresholds - Station name setting — persisted in auth file, served on conditions page - Change password form in settings (no recovery flow needed) Server: - GET/POST /api/dashboard/station-name - POST /api/dashboard/change-password - GET /api/station/monthly-summary - GET /api/station/trend - GET /api/subscriptions, POST /api/subscriptions/thresholds - /api/conditions/public includes stationName field Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
