100%/A: S5F7/F8 list enabled alarms 
Closes the small remaining hole in Alarm Management.  S5F7 is
header-only; S5F8 has the same wire shape as S5F6 (vector of
<L,3 <B ALCD> <U4 ALID> <A ALTX>>) but only includes alarms whose
enabled flag is set.  Codegen handles both as a list_of with
struct_name=AlarmListing; server pre-computes the per-row ALCD from
(severity_category, active state) before passing the rows in.

COMPLIANCE.md: Alarm Management Additional capability flips ✅.

Tests: 78 cases / 454 assertions.
