- New services/te_calendar.py: fetch_upcoming(weeks_ahead) calls TE API
for 9 countries (USD/EUR/GBP/JPY/AUD/CAD/NZD/CHF/CNY), converts to
ff_calendar format, upserts with source='te_api'
- New endpoints: GET/POST /api/eco/te-key, POST /api/eco/te-sync,
GET /api/eco/te-sync/status
- Daily scheduler in main.py: FF live sync + TE sync (if key configured)
run 60s after startup then every 24h
- CalendarPage: TEPanel with key input (password field, Enter to save,
"Get free key" link to tradingeconomics.com/api/login),
"Sync upcoming (6 weeks)" button with polling
FF HTML scraper kept as fallback but TE API is the primary source
for upcoming forecasts (no Cloudflare blocking on server IPs).
