Pull request overview

This PR migrates configuration and routes data from legacy .txt formats to structured /config/config.json and /config/routes.ndjson, centralizes file validation, and removes the intermediate routes DB layer to simplify storage and loading.

Changes:

• Added utils/file_checker.py with JSON/NDJSON validators and wired it into config/routes loading and the web update upload flow.
• Switched runtime file paths to config.json / routes.ndjson, updated UI selection display logic, and adjusted request size limits for web uploads.
• Removed legacy config.example text template and deprecated routes “DB refresh” flow in favor of directly reading NDJSON.
