feat(cloudformation): add parent resource selection for related resou…

[gemammercado]

…rces

Problem

When multiple resources of the same type exist (e.g., MyRole1, MyRole2), the system automatically uses the first one found during the Add Related Resources workflow, giving users no control over which instance is referenced in !Ref/!GetAtt.

Solution

Show resource types first, then logical IDs if duplicates exist

• Pass selected parentLogicalId through LSP protocol
• Update both client and LSP server to handle specific parent selection
