chore(deps): update huangdijia/php-coding-standard to ^2.4 (#911)

* chore(deps): update huangdijia/php-coding-standard to ^2.4

Updates the PHP coding standard package from ^2.0 to ^2.4 to get the latest improvements and fixes.

* style: apply PHP coding standard fixes after updating to ^2.4

Reorders union types to follow null-first convention and applies other
code style improvements as required by the updated huangdijia/php-coding-standard package.

This commit includes automatic fixes across multiple components:
- Union type reordering (Type|null → null|Type)
- Consistent formatting and style improvements
- No functional changes, only code style compliance
