Feature: #105742 - Synchronized manipulation of all crop variants 

Description 

The image manipulation wizard allows images to be cropped to multiple crop variants. When many variants were present, each had to be edited individually, requiring the same changes to be applied multiple times. This was particularly tedious when an editor needed identical crop values across all image variants.

This feature introduces a checkbox that allows editors to crop all image variants simultaneously. This checkbox is available if all crop variants share identical aspect ratios and configuration (except for the title).

excludeFromSync is a new sub-option of the cropVariants TCA/TCEFORM configuration array which allows developers to exclude specific crop variants from synchronized cropping.

This is useful, for example, when adding a special crop variant for a list view that has a different configuration, while still allowing other crop variants to be synchronized.

Example 

The following example defines standard crop variants for a Bootstrap-based template.

All crop variants are configured identically (except for the title), which enables synchronized cropping.

An additional crop variant for the tx_news list view is defined. The option excludeFromSync = 1 ensures that this variant is excluded from synchronization.

TCEFORM.sys_file_reference.crop.config.cropVariants {
    xxl {
        title = Very Large Desktop
        selectedRatio = NaN
        allowedAspectRatios {
            # [...] array of defined aspect ratios (identical!)
        }
    }

    xl {
        title = Large Desktop
        selectedRatio = NaN
        allowedAspectRatios {
            # [...] array of defined aspect ratios (identical!)
        }
    }

    # [...]
}

# Override for news extension
TCEFORM.tx_news_domain_model_news.fal_media.config {
    overrideChildTca.columns.crop.config.cropVariants {
        listview {
            title = List view
            selectedRatio = default
            excludeFromSync = 1
            allowedAspectRatios {
                # [...] array of custom aspect ratio definitions
                # (or identical aspect ratios, but not considered for
                # synchronized cropping)
            }
        }
    }
}

Impact 

Editors can now apply changes to image aspect ratios and cropping to multiple matching crop variants in the image manipulation wizard.

Specific cropVariants can be excluded from synchronization.
