Fix Coding Standards

Problem/Motivation

Running PHPCS against the module reports some coding standards violations. These include missing PHPDoc comments, arrays that do not follow the recommended multiline format, and unnecessary string concatenation. Addressing these issues will improve code quality and help the module comply with Drupal coding standards.

Steps to reproduce

1. Install PHP_CodeSniffer and Drupal coding standards.

2. Run PHPCS against the module.

3. Review the reported coding standards violations.

Example:
phpcs --standard=Drupal web/modules/contrib/entity_notification

Proposed resolution

• Add missing PHPDoc comments.
• Convert arrays to the recommended multiline format where applicable.
• Remove unnecessary string concatenation.
• Update code to comply with Drupal coding standards.

Remaining tasks

• Review the proposed changes.
• Test the patch.
• Commit the changes.
