Fix 001_init.js database column mismatch

- Removed must_change_password field that doesn't exist in admin_users table
- Changed from using db to knex parameter for database operations
- Fixed require statement that was accidentally changed
- Updated security message to reflect no forced password change
- Removed debug logging after identifying the issue

The error occurred because 001_init.js was trying to insert a column
that doesn't exist in the admin_users table schema created by
initializeDatabase().
