Migrate deployment from DigitalOcean to Unraid

Remove:
- .do/app.yaml, .do/deploy.template.yaml
- .github/workflows/deploy.yml (DO App Platform pipeline)

Add:
- deploy.sh (SCP-based deploy to Unraid nginx)

New stack:
- Gitea bare repo on Unraid (/mnt/cache/docker/gitea)
- Ruby container builds Jekyll on push via post-receive hook
- Nginx serves static site on port 8100
- Caddy proxies simcoetradesjournal.krisforbes.ca + simcoetradesjournal.ca
