fix: move Worker config to separate file for Pages compatibility

Move wrangler.toml to worker/wrangler.toml to separate Worker and Pages configurations.
Cloudflare Pages was trying to read wrangler.toml and failing because it contained
Worker-specific configuration (Durable Objects, migrations, etc.) that Pages doesn't support.

Changes:
- Move wrangler.toml → worker/wrangler.toml
- Update deploy scripts to use --config worker/wrangler.toml
- Pages deployment now uses Cloudflare dashboard configuration only

This resolves the deployment error:
"Configuration file cannot contain both 'main' and 'pages_build_output_dir'"
