"""Seed the 2026-07 admin sidebar menus (AKN) that have no other seeder.

Run after migrating:  python master_seeder/seed_akn_updates.py

Adds these admin-only left-side menu items (their pages exist in the frontend
but were previously not seeded anywhere) as CHILDREN of the 'Master Data' group:

    Login History          /admin/login-history
    AI / LLM Providers     /admin/llm-providers
    AI Ranking Parameters  /admin/rank-parameters

They are admin_only=True with blank permission_code (admins see everything),
sitting under the existing 'Master Data' parent alongside its other children.

Also removes the deprecated 'Draft Candidates' child menu.

Idempotent — keyed on `route`, safe to re-run.
