Fixes: #20341

Older installations may still have the legacy django_admin_log table from the Django admin UI. These records can hold a foreign key to existing users and block their deletion. This PR adds a simple migration that drops the table (and its sequence) if they exist, unblocking user deletions on upgraded deployments.

Refs #20338

Drop legacy django_admin_log via raw SQL (DROP TABLE IF EXISTS).
Also drop leftover sequence (DROP SEQUENCE IF EXISTS).
Reverse is a no‑op; no models changed.

Testing

Verified end‑to‑end:

Install fresh NetBox v3.7.8 (with Django Admin UI).
Create a superuser and a user user1 with staff & superuser status.
Log in as user1 and open Django Admin.
Create a django_admin_log entry by creating a “nonce” with random values.
Upgrade to NetBox v4.3.7.
Try to delete user1 → FK error reproduced.
Upgrade to NetBox v4.4.0 and apply this migration.
Delete user1 successfully (no error).
