Pull Request Overview
This pull request refactors a complex SQL query method in the DoctrineSpeakerRepository to use Common Table Expressions (CTEs) for better readability and maintainability. The refactoring transforms a deeply nested query with multiple UNION operations into a cleaner CTE-based approach.
- Replaced complex nested queries with CTEs (QualifiedEvents, SpeakerIds, SpeakerRows)
- Changed IFNULL to COALESCE for better SQL standard compliance
- Improved code formatting and added comprehensive inline documentation

The method is missing its PHPDoc comment. This is a public API method that should have proper documentation describing its parameters and return type.

The Featured column logic has changed from using EXISTS to checking if a JOIN result is NOT NULL. This could potentially affect performance and behavior if there are multiple matching records in Summit_FeaturedSpeakers table, unlike the original EXISTS which was guaranteed to return boolean.
