feat(helpdesk): add Software Products page with BC contract type sync

Add a new Software-Produkte feature to the helpdesk module that syncs
contract types (Create_SaaS_License=true) from BC OData into a local
database table with a nightly scheduler job, providing a Grid.js list
page and detail/edit page for managing custom product names.

- DB migration 003: helpdesk_software_products table (code UNIQUE key)
- BcODataGateway: FS_Contract_Types entity with SaaS filter + fallback
- SoftwareProductRepository: upsert, listPaged, softDelete, updateName
- SoftwareProductSyncService: fetch → upsert → soft-delete lifecycle
- SoftwareProductSyncJobHandler: daily at 02:00 via scheduler platform
- SoftwareProductService: web UI business logic with validation
- Permission: helpdesk.software-products.manage (nav-gated)
- List page: Grid.js with Code, BC Description, Name, Status columns
- Detail page: Code/BC Description read-only, Name editable, PRG pattern
- i18n: de + en translation keys
