decorators: Automatic Primary Key Prop

[Daniel-Boll]

For the basic scenario of a single partition key, it should be possible to automatically add the PrimaryKeyProp type within the decorator itself. This would simplify the model definition and reduce boilerplate code.

Current Example:

@Model("users")
class User extends BaseModel {
	@Column({ partitionKey: true })
	id: Uuid;

	@Column()
	name: string;

	@Column()
	address: string;

	[PrimaryKeyProp]?: [["id"]];
}

Proposed Change:

Automatically include the PrimaryKeyProp based on the partitionKey annotation:

@Model("users")
class User extends BaseModel {
+	@Column({ partitionKey: true })
	id: Uuid;

	@Column()
	name: string;

	@Column()
	address: string;

-	[PrimaryKeyProp]?: [["id"]];
}

Goal:

The goal is to validate if this approach is feasible and, if so, implement it. By using the partitionKey annotation within the column decorator, we should be able to automatically define the primary key property. This enhancement aims to streamline the model definition process and improve developer experience.
