Append all children of editors parent node to element

Fixes a regression introduced by #6972, that resulted in elements that got appended to the editors parent node staying detached. E.g. the drag handle plugin is affected by this regression.

1. Added an optional createCustomHandle callback to ResizableNodeView, allowing developers to fully customize resize handles. When provided, it replaces the default handle creation and bypasses the built-in positionHandle logic, giving complete control over markup, styling, and positioning while preserving backward compatibility.
2. Removed predefined inline styles from the wrapper element to better support dynamic alignment. This eliminates the need for !important overrides in user styles.
3. Added an editor update event listener to dynamically attach or remove resize handles based on the editor’s editable state. The implementation tracks the previous editable state to avoid unnecessary re-renders.

Implement position mapping using the MappablePosition class. This enables position mapping in collaborative editing scenarios.

• Introduce MappablePosition class in core with position, fromJSON, and toJSON methods
• Add editor.utils property with getUpdatedPosition(position, transaction) and createMappablePosition() methods
• Create CollaborationMappablePosition subclass that extends MappablePosition with Y.js relative position support

Improve TypeScript generics for Node.extend

The Node.extend method's TypeScript signature was updated so that ExtendedConfig can extend NodeConfig and MarkConfig, improving type inference when extending Node and Mark classes with additional config properties.

This is a type-only change — there are no runtime behavior changes.
