Update DoorDash ordering CTAs and smart button (#33)

## Summary
- Switch Skillet'z online ordering CTAs to DoorDash Storefront
(`order.online`) using a shared DoorDash config.
- Add DoorDash's site-wide floating `ORDER ONLINE` smart button via the
Storefront SDK.
- Update `/order-online` copy to “Track and manage your order online.”
and simplify the buttons to `Order Pickup` / `Order Delivery`.
- Style ordering CTAs consistently: DoorDash red (`#eb1700`) for the
order page buttons and header nav button; rounded `8px` corners for the
floating smart button.
- Keep Tea-Rek'z `/order-online-tearekz` pointed at Toast by decoupling
its redirect from Skillet'z ordering partner config.
- Rebuild the generated GitHub Pages `docs/` output.

## Analytics
- The `/order-online` clickouts continue to use the existing Google
Analytics outbound click tracking helper.
- The pickup/delivery links emit labels like `order_online:pickup` and
`order_online:delivery` with destination URL/domain/page context.

## CI / validation
- `npm run lint` (passes; existing `<img>` warnings only)
- `npm run format:check`
- `make build`
- GitHub Actions `build` check is green

## Notes
- `order.online` blocks direct bot/link-check fetches with Cloudflare,
so Proof HTML ignores that domain and the DoorDash-provided Storefront
URL is treated as authoritative.
- This PR only prepares the change; it has not been merged or deployed.
