[ildyria]

This pull request introduces a feature for extracting dominant colors from images, along with supporting changes to integrate and test the functionality. The most significant changes include the addition of a new job for color extraction, a helper class for image processing, and updates to the database and configuration to enable this feature. Below is a breakdown of the key changes by theme:

Color Extraction Feature:

• app/Jobs/ExtractColoursJob.php: Added a new job class, ExtractColoursJob, to extract the five most dominant colors from an image and store them in the database. It supports both GD and Imagick drivers for image processing.
• app/Image/Handlers/ImageFactoryForColourExtraction.php: Introduced a helper class, ImageFactoryForColourExtraction, to create image instances using either the GD or Imagick libraries for color extraction.

Database and Configuration Updates:

• database/migrations/2025_06_04_193132_optional_color_extraction.php: Added a migration to introduce a new configuration option, extract_colours_from_image, allowing users to enable or disable color extraction.
• app/Http/Middleware/ConfigIntegrity.php: Updated the configuration integrity check to include the new extract_colours_from_image setting.

Enhancements to Models:

• app/Models/Colour.php: Added a static method, fromHex, to create or update Colour instances from hexadecimal strings.
• app/Models/Palette.php: Added a method, fromHex, to convert hexadecimal color strings to integer representations for storage.

Dependency and Testing:

• composer.json: Added the farzai/color-palette library as a dependency for color extraction functionality.
• tests/Feature_v2/Jobs/ExtractColoursJobTest.php: Created a test suite to validate the ExtractColoursJob, ensuring it works correctly with both GD and Imagick drivers.

These changes collectively enable the extraction and storage of dominant image colors, providing a foundation for enhanced image-related features.
