[admin/api] Make batch user creation organization field readonly #609

This change prevents modification of the organization field for existing
RadiusBatch objects in both admin interface and REST API. When editing
existing batch objects, the organization field is now readonly to maintain
data integrity and prevent accidental organization changes.

Changes:
- Added organization field to readonly_fields in RadiusBatchAdmin for existing objects
- Created RadiusBatchUpdateSerializer with organization as readonly field
- Added BatchUpdateView for handling batch detail API operations
- Added comprehensive tests for both admin and API readonly functionality

Fixes #609
