feat(table): support embeddable question types inside table columns

[alisher372]

Summary

Add support for embeddable question types inside table question columns.

Instead of knowing about specific plugins, the table question now delegates rendering to any question type implementing the new embeddable interface.

What is implemented

• support for embeddable question types;
• dynamic column configuration loading;
• embedded administration rendering;
• embedded end-user rendering;
• server-side rendering for dynamically added table rows;
• validation and preparation of embedded question extra data.

Why server-side row rendering?

Originally, additional table rows were created entirely in JavaScript.

This approach worked for built-in question types because their client-side configuration was sufficient to recreate the controls.

With embeddable question types, this is no longer enough. Embedded question types are responsible for rendering and initializing their own controls, which may include server-generated markup, unique identifiers and initialization logic.

To keep this responsibility inside each question type and avoid duplicating rendering logic in JavaScript, newly added rows are now rendered on demand by the server through a dedicated controller. The controller simply exposes the existing row rendering logic already used for the initial table rendering, ensuring that dynamically added rows behave exactly like the initially rendered ones.

Motivation

The table question previously only supported built-in question types.

With this change, any question type implementing the embeddable interface can be used inside a table without introducing plugin-specific rendering logic into Advanced Forms.

Backward compatibility

Existing built-in question types continue to work exactly as before.

Plugins that do not implement the embeddable interface are unaffected.
