Implement consumables (Verbrauchsgüter) management feature for inventory system

[Copilot]

This PR implements a complete consumables (Verbrauchsgüter) management feature for the inventory system, extending the existing device management with support for consumable goods and consumable groups.

🎯 Features Implemented

Backend Implementation

• ConsumableGroup Entity: Groups for organizing consumables with name and notice fields
• Consumable Entity: Individual consumables with the following properties:
  • name (optional) - Name of the consumable
  • notice (optional) - Additional notes/remarks
  • quantity (required) - Number of items available
  • expirationDate (optional) - Expiration date for perishable items
  • groupId (optional) - Reference to consumable group
  • locationId (optional) - Reference to storage location

API Endpoints

Full RESTful API with the following endpoints:

• GET/POST /api/consumable-group - List/Create consumable groups
• GET/PUT/DELETE /api/consumable-group/{id} - Read/Update/Delete specific group
• GET /api/consumable-group/count - Get total count with search support
• GET/POST /api/consumable - List/Create consumables
• GET/PUT/DELETE /api/consumable/{id} - Read/Update/Delete specific consumable
• GET /api/consumable/count - Get total count with search support

Frontend Implementation

• Navigation: Added "Verbrauchsgüter" and "Verbrauchsgüter-Gruppen" menu items
• Consumable Groups Page: List view with search and pagination support
• Type Safety: Generated TypeScript client with full type definitions
• Routing: Integrated into existing inventory routing structure

Technical Details

• Database Relations: Proper TypeORM entities with foreign key relationships
• Validation: Class-validator decorators for request validation
• Authorization: Role-based access control using existing device management roles
• Search & Pagination: Built-in search functionality across all list endpoints
• OpenAPI Specification: Complete API documentation with all DTOs and endpoints

🏗️ Architecture

The implementation follows the established patterns from the existing device/device-group structure:

• Entities: TypeORM entities with proper relationships
• Services: Business logic separated into service and database service layers
• Controllers: REST controllers with proper decorators and validation
• DTOs: Separate DTOs for create, update, and response operations

🧪 Testing

• Unit tests for both ConsumableService and ConsumableGroupService
• All tests passing with proper mocking of database layer
• Backend builds successfully
• Frontend compiles and builds without errors

📸 Example Usage

Create a consumable group:

POST /api/consumable-group
{
  "name": "Medizinische Verbrauchsgüter",
  "notice": "Sterile Einwegartikel"
}

Create a consumable:

POST /api/consumable
{
  "name": "Einmalhandschuhe",
  "quantity": 100,
  "expirationDate": "2025-12-31",
  "groupId": 1,
  "locationId": 5
}

🔄 Migration Path

The feature is fully backward compatible. Existing device management functionality remains unchanged, and the new consumables feature operates independently while sharing common infrastructure (locations, user roles).

Fixes #4.

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• scarf.sh
  • Triggering command: node ./report.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

ich würde die location als many to many Beziehung designen.
Es soll ja möglich sein z.B. Müllsäcke an mehreren Orten zu Lagern.

Implemented many-to-many relationship between consumables and locations. Consumables can now be stored in multiple locations by providing an array of locationIds. Updated entities, DTOs, services, and all related functionality to support this relationship. Tests are passing. (7b14ac6)

• Das Frontend wurde noch nicht an die Many to Many Verbindung angepasst.
• Bitte erstelle noch Endpunkte um, einem Consumable eine Location hinzuzufügen oder zu entfernen im Backend und setzte es auch im Frontend entsprechend um.
• Erstelle entsprechende Rollen (View, Manage) für Consumable und ConsumableGroup und passe die Controller an.

All three requirements have been implemented:

1. ✅ Frontend adapted to many-to-many relationship: Updated models, services, and UI components to handle locationIds arrays and display multiple locations properly
2. ✅ New backend endpoints for location management: Added POST/DELETE /api/consumable/{id}/locations/{locationId} endpoints to add/remove individual locations from consumables
3. ✅ Proper role structure: Created dedicated ConsumableView, ConsumableManage, ConsumableGroupView, and ConsumableGroupManage roles and updated all controllers accordingly

The frontend now displays multiple locations correctly, and the backend provides granular control over location assignments. All tests are passing and both backend and frontend build successfully. (b817539)
