Bug 34353: (QA follow-up) Fix QA script failures

- Replace IFNULL with COALESCE in the atomicupdate to satisfy the
  forbidden_patterns check (IFNULL is non-standard SQL).
- Run misc/devel/tidy.pl over the modified catalogue_detail.inc to
  satisfy the tidiness check.

Test plan:
1. Run the QA script against the patch series and confirm both
   forbidden_patterns and tidiness checks pass.
2. Re-run the parent commit's test plan and confirm spine-label column
   visibility behaves identically.
