Fix PHP CodeSniffer linting errors

[jsirish]

The CI workflow is failing due to PHP CodeSniffer linting errors. These need to be addressed to ensure code quality standards are met.

Issue

The phpcs linting step is reporting errors that prevent the CI from passing.

Acceptance Criteria

• All phpcs linting errors are resolved
• CI phpcs step passes successfully
• Code follows the project's coding standards defined in phpcs.xml.dist

Additional Context

This issue was identified during PR review when attempting to add GitHub Sponsors funding configuration. The linting errors are unrelated to the funding changes and should be addressed separately.
