Added UUID Field Type Support for Custom Fields

  • customField.create now supports creating custom fields with the UUID field type.
  • customField.setValue and customField.setValues now accept UUID string values for UUID-type custom fields. The value must be a valid UUID string (e.g., 550e8400-e29b-41d4-a716-446655440000).
  • Fixed a validation bug where non-string values passed to UUID fields were incorrectly accepted instead of being rejected.
