Refactor: Use addEventListener for remove button click handler

[pyob-bot]

Summary of Changes

This pull request updates the event handling mechanism for the 'remove' button within the dashboard's queue items. The onclick property has been replaced with addEventListener('click', ...) to attach the handler for removing a queue item.

Technical Impact

• Modern Event Handling: Transitions to the recommended and more flexible addEventListener API for attaching event handlers in JavaScript.
• Improved Maintainability: addEventListener allows for better separation of concerns by detaching event registration from direct property assignment, making the code cleaner and easier to manage.
• Consistency: Promotes a consistent pattern for event handling across the codebase, aligning with modern JavaScript best practices.
• No Functional Change: This change is purely an internal refactor and does not alter the user-facing functionality or behavior of the remove button. The button will continue to remove items from the queue as before.
