feat: add СХД configuration type with storage-specific tabs and LOT catalog guide

- Add config_type field ("server"|"storage") to Configuration and LocalConfiguration
- Create modal: Сервер/СХД segmented control in configs.html and project_detail.html
- Configurator: ENC/DKC/CTL categories in Base tab, HIC section in PCI tab hidden for server configs
- Add SW tab (categories: SW) to configurator, visible only when components present
- TAB_CONFIG.pci: add HIC section for storage HIC adapters (separate from server HBA/NIC)
- Migration 029: ALTER TABLE qt_configurations ADD COLUMN config_type
- Fix: skip Error 1833 (Cannot change column used in FK) in GORM AutoMigrate
- Operator guide: docs/storage-components-guide.md with LOT naming rules and DE4000H catalog template
