Drupal 11 + Imagemagick 4 compatibility

Problem/Motivation

The automated fixes update only the version constraints. Drupal 11 needs PHP 8.3 for minimum stability, which means Drupal 10.1 is out. The Imagemagick → 8.3.x doesn't have Drupal 11 version, so need to use 4.0.x But 4.0.x has a requirement of Drupal 10.3, so we have to use the same.

Also need to check PHP8.3 code compatibility.

Proposed resolution

• Adjust requirements in composer.json and module.yml.
• Fix php version compatibility.
• Remove bad patterns.
• Cleanup code.

Remaining tasks

Write tests?
Add new features?
