The academy identity is now established by the seeder (from ACADEMY_NAME_EN,
ACADEMY_NAME_AR env vars). The wizard no longer has an "Academy Profile" step.
It starts directly at Branches (step 1) and only configures operational data:
branches, activities, programs, facilities, groups, staff, settings.

This enforces one-academy-per-instance: the academy exists before the wizard
runs, and no user action can create or duplicate it.
