asap-tools: calculate_fidelity never scores SQL queries #885

calculate_fidelity.py never scores SQL queries: the ClickHouse client stores ClickHouse's TabSeparated text in QueryResult.raw_text_result and leaves result as None, and get_all_timeseries only reads result. So every SQL query (ASAPQuery's ClickHouse adapter also answers in TabSeparated) yields no time series and no score.

Fix: parse TabSeparated rows (group-by columns → labels, last column → value) into the same keyed form result uses, so SQL queries are scored like PromQL ones.
