Add automatic database population from PDGA numbers file at startup

- Read pdga-numbers.txt at server startup and check for missing players
- Automatically scrape and populate any missing players into database
- Maintain respectful 2-second delays between PDGA requests
- Add comprehensive logging for population process
- Include new API endpoints for manual database population and status checking
- Ensure database is fully populated before server accepts requests
