New features:
- ActivityController and manager for CW sales activities (CRUD)
- ForecastProductController for opportunity forecast/product lines
- CW member cache with dual-layer (in-memory + Redis) resolution
- Catalog category/subcategory/ecosystem taxonomy module
- Quote statuses type definitions with CW mapping
- User-defined fields (UDF) module with cache and event refresh
- Company sites CW module with serialization
- Procurement manager filters (category, ecosystem, manufacturer, price, stock)
- Opportunity notes CRUD and product line management via CW API
- Opportunity type definitions endpoint

Updates:
- OpportunityController: CW refresh, company hydration, activities, custom fields
- UserController: cwIdentifier field for CW member linking
- CatalogItemController: category/subcategory fields from CW
- PermissionNodes: sales note/product CRUD nodes, subCategories, collectPermissions
- API routes: procurement categories/filters, sales notes/products, opportunity types
- Global events: UDF and member refresh intervals on startup

Tests (414 passing):
- ActivityController, ForecastProductController, OpportunityController unit tests
- UserController cwIdentifier tests
- catalogCategories, companySites, memberCache, procurement module tests
- activityTypes, opportunityTypes, quoteStatuses type tests
- permissionNodes subCategories and getAllPermissionNodes tests
- Updated test setup with redis mock, API method mocks, and builder helpers
