refactor(coingecko.php): streamline currency data update process

Browse source 
Consolidated currency list initialization and improved data fetching from CoinGecko API. Enhanced error handling for CURL requests. Optimized the logic for updating and saving currency data, ensuring more efficient and readable code. Ensured data write-back occurs only when sufficient time has elapsed since the last update.
