Replace internal todos with Vikunja API wrapper

- New app/vikunja.py: get_tasks, create_task, update_task, delete_task
- /todos page now reads from and writes to Vikunja (create, mark done, delete)
- Auto-todos (clean build plate, filament low) post to Vikunja after DB commit
- /api/todos router proxies to Vikunja
- .env.install: VIKUNJA_URL, VIKUNJA_API_TOKEN, VIKUNJA_PROJECT_ID
