feat(schema-compiler): Add join_path support in folder includes

[ovr]

Adds support for using join_path syntax within folder includes to reference all members from a specific cube in the view's join graph. This allows folders to aggregate members from multiple nested join paths plus direct field references.

Example:

views:
  - name: Ecom
    cubes:
      - join_path: orders
        includes: "*"
      - join_path: orders.users
        prefix: true
        includes:
          - count
          - gender
      - join_path: orders.products
        prefix: true,
        includes:
          - category_id
    folders:
      - name: Mixed
        includes:
          - join_path: orders
          - join_path: orders.users
          - products_category_id
