feat: use cloudflare-pages-plugin-trpc

[uxduck]

This is not yet working. Building (pnpm dev) gives an error:

pnpm dev                                                                                                                                                          INT ✘  06:48:00 pm

cloudflare-pages-plugin-trpc doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module (i.e. it doesn't have "type": "module" or an .mjs extension for the entry point). Please contact the package author to fix.
