Subject: [PATCH] refactor: Move billing module assets to vendor package
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BREAKING CHANGE: All billing-related frontend code moved to billing module

Changes:
- Remove billing Vue components from core (InvoiceForm, InvoiceManagement, etc.)
- Remove billing config from core (billing_module.yaml)
- Update router.js to dynamically load billing routes from module
- Update Dashboard.vue to dynamically load InvoicesDashboardWidget
- Add webpack alias '@billing-module' pointing to vendor/mycrm/billing-module
- Billing module is now fully self-contained

The billing module now exports:
- routes.js: Route definitions for /billing/* paths
- components.js: Reusable components (InvoicesDashboardWidget)
- index.js: Main module exports

Frontend assets are loaded via '@billing-module' alias in webpack.
