feat: add periodic background data update task

Replaced the cron job for updating data with a background
thread that runs every 5 minutes within the Flask app. Updated
version to 0.3.7.

This change ensures data is refreshed regularly without
external dependencies like cron, improving deployment
simplicity and reliability.
