fix: fix Cloudflare Workers CI build by resolving typescript peer dependency

The Cloudflare Workers CI build was failing due to an ERESOLVE error related to a conflicting typescript peer dependency in `react-scripts`.
This commit updates `wrangler.toml` to add `--legacy-peer-deps` to the frontend `npm install` build command, allowing the build to bypass the conflict and compile successfully.
