Fix ExtractableTargetElement enum

- Remove inconsistent REE_ prefix, use standard element symbols
- Add human-readable titles (e.g., "Lanthanum" not "REE_LA")
- Add proper descriptions with context about element uses
- Add CHEBI ontology mappings for all elements
- Add aliases matching CHEBI labels for validation
