feat(medusa,pricing): Cart pricing context with customer group (#10579)

* fix(carts): Fixes cart modifications not accounting for certain price lists (#10493)

*What*

* Fixes #10490
* Expands any available customer_id into its customer_group_ids for cart
  updates that add line items.

*Why*

* Cart updates from the storefront were overriding any valid price lists
  that were correctly being shown in the storefront's product pages.

*How*

* Adds a new workflow step that expands an optional customer_id into the
  customer_group_ids it belongs to.
* Uses this step in the addToCartWorkflow and
  updateLineItemInCartWorkflow workflows.

*Testing*
* Using medusa-dev to test on a local backend.
* Adds integration tests for the addToCart and updateLineItemInCart
  workflows.
