New GET /history endpoint fetches 365 days of BTC/EUR data from CoinGecko, deduplicates by date, and joins the user's purchases. BTCHistoryChart component renders the price line with orange dot markers on purchase dates and a dashed cyan avg buy price line. Tooltip shows purchase details on marked dates.
