Courses without scraped layouts can now be used in tours by entering
a layout name and par manually. The layout is saved to the database
for reuse. All courses are shown in the dropdown, not just those with
existing layouts.
Players can create tours with selected courses/layouts and a date range.
Others join via a 6-character tour code, play the courses, and report
their total strokes. Live leaderboard with points and +/- par display.
Includes: database schema, model, service, routes, views, and styling.

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
