fix(tinybird): fail loudly on invalid query_pipe parameters JSON

parsePipeParameters previously returned {} on any JSON parse error, so a
mistyped 'parameters' input produced a successful pipe call with the dynamic
filters silently dropped. Throw a clear error for non-empty, non-object input
instead; an omitted/empty value still means 'no parameters'.
