* fix: support accessibility tree refs in upload command (#1107)
The upload command only accepted CSS selectors while click/fill supported
accessibility tree refs (e.g. e1, @e1, ref=e1). This resolves the API
inconsistency by reusing resolve_element_object_id for all selector types.
* style: apply cargo fmt
