📋 Warden: Refactor Widget Render Methods for Security and Maintainability

[mdjwel]

This PR refactors several Elementor widgets to remove the use of extract( $settings ) in their render() methods.

Why:

• extract() pollutes the symbol table and makes it difficult to trace variable origins.
• It can lead to unintentional variable overwrites.
• Removing it improves code clarity, maintainability, and security.
• The PR also fixes some non-standard logic checks (e.g., !empty($var == 'val')) and enforces strict comparisons.

Changes:

• Refactored Accordion, Icon_Box, Tabs, Video_Popup, Counter, Team_Carousel, and Video_Playlist widgets.
• Explicitly defined variables required by templates or updated templates to use $settings directly.
• Standardized array syntax and comparisons in modified files.

Testing:

• Verified PHP syntax using php -l on all modified files and their templates.
• Verified that templates use $settings or explicitly defined variables.
