Allow users to add themselves to the player database through a web form,
eliminating the need for manual pdga-numbers.txt updates. Implement 24-hour
rate limiting on prediction refreshes to prevent abuse while maintaining
reasonable update frequency.
Key changes:
- Add player self-registration with PDGA number lookup and confirmation
- Store predicted ratings in database for persistence across restarts
- Implement 24-hour rate limit on prediction refresh endpoint
- Make database the single source of truth (text file only for initial seed)
- Remove "Scrape All Layouts" bulk operation button
- Update "Load All" to refresh existing players instead of text file
