Subject: [PATCH] fix: Convert UUIDField columns to uuid type for MariaDB

Converts UUIDField columns from char(32) to uuid type for MariaDB Django 5 compatibility.

This migration converts 3 UUIDFields:
- subsidy_subsidy.uuid
- subsidy_subsidy.enterprise_customer_uuid
- subsidy_subsidyroleassignment.enterprise_id

See: https://docs.djangoproject.com/en/5.2/releases/5.0/#migrating-uuidfield
