fix Cloudflare deploy: add wrangler devDep and --config flag

The Astro cloudflare adapter generates wrangler.json in dist/server/
with the correct main and assets paths. The root wrangler.toml only
has name and nodejs_compat since adding main causes a chicken-and-egg
build failure. Deploy command passes --config to point at the
generated config.
