Returns rates for a given date: today uses latest DB row, past dates
check DB first then fetch from Frankfurter and persist for caching.
Future dates and invalid formats return 400.

Store daily exchange rates in PostgreSQL with EUR/DKK cross rate.
Seed rates atom from DB on startup so WebSocket works immediately
even if Frankfurter is unreachable.

Use POST /v1/currency-exchange-quotes to get actual buy price including
spread, matching the Strike app. Fee is cached daily to calculate the
pre-fee amount from the configured total (default 55 EUR). Store
quote_sats in the strike_price DB table.

- Poll Strike API every 10s, store all rates as JSONB in strike_price table
- Move Docker env vars to .env file, use shared network for cross-project communication
- Add startup retry (5x 5s) for Frankfurter poller to handle container race condition

Polls self-hosted Frankfurter API hourly for USD-based EUR and DKK exchange
rates. Both the WebSocket HTML fragments and the /api/price/latest JSON
endpoint now include the currency rates alongside BTC price.

Split from btcprice monolith. Owns DB, migrations, Binance WebSocket,
Kraken OHLC pollers, and exposes a JSON API with SSE price stream.
