StatusBadge: fix normal badge — only check status_code, not text

The previous condition 'c === "normal" && !t' required status_text to be
empty, but enriched records carry text suffixes like '正常 + CL4h' which
are truthy and dropped normal records into the '異常' fallback.

3 Kaka records (id=22/28/30) were affected — act_in 10:38/10:43 (early),
act_out 20:00 (on time), so they should render the green '正常' badge but
were showing '異常' instead.
