fix(test): kebab testNames for section-loading E2Es to match TOUCHFILES keys

The two section-loading E2E tests used display-form testNames ('/ship
section-loading', '/plan-ceo-review section-loading') while every other E2E
testName and their E2E_TOUCHFILES keys are kebab. The completeness gate does an
exact `name in E2E_TOUCHFILES` check, so it failed (pre-existing on main); diff-
based selection also couldn't match them. Align to ship-section-loading /
plan-ceo-section-loading.
