Enable Puma early hints support in all Procfiles

Added --early-hints flag to all Procfile configurations to enable
Puma's early hints support. This allows Rails to send HTTP 103 Early
Hints responses with preload headers for better performance.

Updated files:
- Procfile (production)
- Procfile.dev
- Procfile.dev-prod-assets
- Procfile.dev-static
- Procfile.dev-static-assets
