added docker-compose with mongo and calchat-server

- drone.yml: deploy_latest Pipeline mit k3s test-backend, OpenTofu
  E2E-VMs, E2E-Test-Ausführung, Email-Notification und Cleanup
- Alte tag/promote Pipelines auskommentiert
- APK build/upload vorerst auskommentiert
- E2E test runner script (scripts/e2e-test.sh)
- tsconfig: expo/tsconfig.base Extension
- CLAUDE.md an neue CI/CD-Struktur angepasst

+The project uses Drone CI (`.drone.yml`). Note: `server_build_and_test` and `check_for_formatting` pipelines are currently commented out.
 
 **On push to main:**
-1. **`server_build_and_test`**: Builds the server (`npm ci` + `npm run build`) and runs Jest tests (`npm run test`)
+1. **`deploy_latest`**: Runs E2E testing pipeline with ephemeral infrastructure:
-2. **`check_for_formatting`**: Checks Prettier formatting across all workspaces (`npm run check_format`)
+   - **`deploy_test_backend`**: Deploys server to k3s cluster (`192.168.178.201`) using `kubernetes/manifest.yml` with commit-based naming (`e2e<sha8>`)
-3. **`deploy_latest`**: Builds Docker image, pushes to Gitea Container Registry (`gitea.gilmour109.de/gilmour109/calchat-server:latest`), then SSHs into VPS (`10.0.0.1`) to pull and restart via `docker compose`. Builds APK via `eas-build` Docker image and creates a Gitea release (title "latest") with the APK. Depends on both pipelines above passing first.
+   - **`create_e2e_vm`**: Provisions ephemeral Android emulator VM on Proxmox via OpenTofu (`tofu/e2e/`)
+   - **`run_e2e_tests`**: SSHs into VM, runs `scripts/e2e-test.sh` (clones repo, starts emulator + Expo + Appium, executes E2E tests). VM IP derived from build number: `192.168.178.$((211 + BUILD_NUMBER % 44))`
+   - **`notify_failure`**: Sends email notification on E2E failure
+   - **`destroy_e2e_vm`**: Tears down VM via `tofu destroy` (runs on success and failure)
+   - **`cleanup_k3s`**: Deletes test backend resources from k3s (runs on success and failure)
