Improving SQL Server setup documentation when using custom types

[ilianiliev-redis]

Note

Low Risk
Documentation-only change with no runtime or configuration impact.

Overview
Adds section 5 to the SQL Server RDI prep guide for custom data types (user-defined types).

It documents granting REFERENCES ON TYPE::<schema>.<type-name> to the Debezium user and calls out a misleading Debezium error when that permission is missing (primary key column not found in the table).
