Adds optional owner_email field to the Create Account modal. Superadmin
can specify an existing user's email to assign as account owner at
creation time. Backend 404s with a clear message if the email is unknown.
Error detail now surfaces to the toast instead of a generic message.

Four places were hardcoded to engineer|viewer only:
- AccountRoleUpdate schema (user.py) — blocked PUT /admin/users/{id}/account-role at the API level
- AdminUserCreate schema (admin.py) — blocked creating users with owner/admin role
- AccountDetailPage role dropdowns (create form + inline member role changer)
- AccountsPage create user role dropdown
Now all four accept the full set: owner, admin, engineer, viewer.

Adds complete super_admin panel with 9 pages and account owner categories page.
Backend includes 5 new DB tables, ~25 API endpoints, settings manager with
in-memory cache, and 29 integration tests. Frontend includes reusable admin
components (DataTable, Pagination, ActionMenu, etc.) with code-split lazy loading.
