fix: add startup diagnostics, switch to azure/webapps-deploy action

- Removed set -e to prevent silent failures
- Added detailed startup diagnostics (Python path, imports, directory listing)
- Tests critical imports before launching gunicorn to surface errors
- Switched from az webapp deploy to azure/webapps-deploy@v3 action
  (more reliable, avoids 502 Kudu warmup issues)
