Add environment-specific PHP configuration files

This commit introduces dedicated PHP configuration files for development and
production environments:

- Add php.dev.ini with developer-friendly settings:
  * Full error reporting and display
  * Xdebug enabled with comprehensive debugging features
  * Generous memory limits and execution times
  * Development-oriented opcache settings with timestamp validation

- Add php.prod.ini with production-optimized settings:
  * Disabled error display (but continued logging)
  * Security hardening with disabled functions
  * Performance tuning with aggressive opcache settings
  * Memory and execution limits optimized for efficiency
  * JIT compilation enabled for PHP 8+
  * Xdebug completely disabled

This approach provides better separation of concerns by moving PHP configuration
from environment variables to dedicated configuration files, offering more
fine-grained control over PHP behavior in different environments.
