Add kw_only to remaining vws.reports dataclasses

[adamtheturtle]

Adds kw_only=True to TargetData, QueryResult, and TargetStatusAndRecord so all dataclasses in this module consistently require keyword arguments. Existing construction sites already use keywords.

Note

Low Risk
Low risk: this only makes TargetData, QueryResult, and TargetStatusAndRecord keyword-only, and existing construction in this module already uses keyword arguments. Risk is limited to any external callers that may still instantiate these dataclasses positionally.

Overview
Makes TargetData, QueryResult, and TargetStatusAndRecord dataclasses in src/vws/reports.py keyword-only by adding kw_only=True, aligning them with the rest of the module’s dataclasses.

This is an API-surface tightening change that prevents positional instantiation of these types while leaving parsing/construction via from_response_dict unchanged.
