Add deployment config and strengthen synopticChart.sh

- Inline DeriveTime from func/deriveTimeString.sh; delete func/
- Add set -euo pipefail, quoting, and stderr for error messages
- Archive PDFs to /var/lib/synoptic/archive/raw/ after conversion
- Publish PNG to /srv/www/synopticLatest.png
- Add systemd units: synoptic.{service,timer}, synoptic-retry.{service,timer}
- Timer fires at 02:10, 08:10, 14:10, 20:10 UTC (2h after BOM publish slots)
- Add nginx site config for pestrel.com
- Add setup.sh (run once on VPS as root) and deploy.sh (run from cr4y)
