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
