Code Cleanup: Remove debug calls and dead code

Problem/Motivation

The codebase contains many commented-out code blocks and development debug calls (dump()). These artifacts should not be present in a production-ready module on Drupal.org.

Proposed resolution

• Remove all dump() calls.
• Delete all blocks of commented-out code.
• Ensure all local variables follow Drupal's camelCase standard.

Remaining tasks

Perform a global cleanup of all files in the src directory.
