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 25 UUIDFields across 4 apps: - content_assignments: 6 fields - core: 1 field - subsidy_access_policy: 7 fields - subsidy_request: 7 fields See: https://docs.djangoproject.com/en/5.2/releases/5.0/#migrating-uuidfield
