Phase 3, Task 3.1 - Frontend View Handlers Implementation

Status: ✅ COMPLETE

Date: 31 January 2026

File Created: /app/modules/locations/frontend/views.py

Overview

Implemented 5 FastAPI route handlers (Jinja2 frontend views) for the Location (Lokaliteter) Module. All handlers render templates with complete context from backend API endpoints.
