fix: Fix migration foreign key constraint and remove seeder

- Change employee_id to INT(10) to match employees.person_id type
- Remove seeder call from migration (causes issues in tests)
- Add permission/module inserts directly in migration
- Add proper down() method to drop FK and data
- Remove seed reference from tests

The foreign key was failing because:
1. employee_id was defined as unsigned INT(11)
2. employees.person_id is INT(10) NOT NULL (not unsigned)
3. Seeder call in migration caused multiple runs in tests
