fix(datetime): replace deprecated utcnow() with timezone-aware equivalent (#15)

- Replaced datetime.utcnow() with datetime.now(timezone.utc) in router and observability modules
- Preserves backwards compatibility with Python 3.10+
- Fixes #14

+Install Model Router and its embedded **AI Traffic Control Room** dashboard directly from PyPI:
+
+```bash
+pip install model-router-cli

+
+### Quick Commands:
+```bash
+# Run system diagnostics & environment checks
+modelrouter doctor

+# Launch the Traffic Control Room Dashboard & API Gateway in your browser
+modelrouter ui --open-browser

+The built-in Typer CLI provides terminal commands for inspection, diagnostics, and testing (use `modelrouter` if installed via pip, or `python backend/app/cli/main.py` from source).

+curl -OJ "http://127.0.0.1:8000/api/traffic/export?format=csv"

+Each export includes the timestamp, request ID, prompt preview, task type, complexity, selected model, input/output/total tokens, cost saved, and total latency. The `format` query parameter accepts only `csv` or `json`.
+
+The same export is available in the frontend under **Traffic**. Select `CSV` or `JSON` beside **Export Telemetry**, then click the button to download the complete historical traffic dataset.
