feat: end to end api type safety with redis rate limiting (#573)
* feat: support hono rpc * add wrangler file * update name of wrangler file * add wrangler as a dependency * add compatibility_flags * trigger ci * core: add health check to docker file * expose port 80 * update custom healthcheck * feat: implement openapi * install dependencies in root * debug yml * update yml * update port * update dockerfile with envs * completely move away from apiClient * rename backend to api * refactor: update server descriptions and comment out local spec saving * update lock file * use api.classroomio.com * add support for redis * fix: add missing line break in WelcomeModal.svelte * refactor: remove wrangler configuration and update Vite config for API integration
