context value dsl

[BykhovDenis]

DSL for SelectedContext. As part of preparation for process dsl and for calculating fields separation. Why we need it? Because old way (JSON) was too big, especially for nested context (real example part on screenshot)

Pull Request Overview

This PR introduces a DSL (Domain Specific Language) for SelectedContext to replace the JSON-based approach for better performance with nested contexts. The DSL provides a more compact representation that reduces payload size significantly.

• Implements a bi-directional DSL parser and serializer for SelectedContext objects
• Updates context parsing to fallback to DSL when JSON parsing fails
• Refactors ProcessAttribute component to use DSL format by default
