Summary by cubic

Fixes DOM element mapping and hashing to preserve empty accessibility names. We keep an empty ax_node.name, include it in hashes, and only use None when the name is missing.

• Bug Fixes
  • Preserve empty ax_node.name in DOMInteractedElement.load_from_enhanced_dom_tree.
  • Include empty names in compute_stable_hash and __hash__ to distinguish empty vs missing.
