fix(test): restore #[test] on the SBC fault guard test

The squad_actives default test was inserted between #[test] and the function
it belonged to, which stacked a duplicate attribute on the new test and left
sbc_post_commit_faults_require_all_staging_guards with none - silently
disabling it while the new test ran twice.

Caught by clippy (-D duplicate-macro-attributes, -D dead-code); the doubled
test name in the earlier run was the tell. Lib tests go 129 -> 131 with both
now executing.
