Segments: The experience of working with Segments and Segmented Blocks

[nielslyngsoe]

Fixes issue where variant inner values of invariant properties(Block Level Variants) does not trigger a Variant-Entry to be made.

As well improves the logic that ensures Variant Entries, so it distributes the knowledge to Variants that matches the values being entered.

This means when editing a Segmented fields (Shared across cultures) then the Matching variant on all Cultures will get a Variant-Entry and appear as something that has data (Not greyed out)

Same for Culture-varying fields, they would match all Segment-Variants on same culture.

As well hint/validation-badges has been updated to work for Segment-Variants:

Pull Request Overview

Enhances the variant handling for segmented fields so that matching variants across cultures/segments get variant entries and correct hint/validation badges. Introduces a flat-mapper to traverse nested property values (e.g., blocks) to determine required variant entries.

• Ensures variant entries are created across matching cultures/segments based on entered values.
• Adds a Property Value Flat Mapper with tests and updates manifests to use forEditorAlias for resolvers.
• Improves UI badges and variant selector hints; minor performance tweak in block list editor updates.
