Summary

This PR introduces explicit type declarations for class constants, leveraging the feature introduced in PHP 8.3.

Motivation

Enhances type safety and static analysis.
Makes code intent clearer.
Prepares PhD for PHP 8.4 compatibility and future strictness.

Scope

Added types such as int, string, bool, or array to class constants.
Example:
Before:
public const FORMAT_HTML = 1;
public const NAME = 'PhD';
After:
public const int FORMAT_HTML = 1;
public const string NAME = 'PhD';

Impact

✅ No runtime behavior change.
✅ Fully backward compatible with PHP 8.3+.
⚙️ Code clarity and safety improvement only.
