refactor: migrate to Nitro 3 and remove authentication

Major refactoring to upgrade the codebase and simplify architecture:

- Upgrade from Nitro 2.x to Nitro 3.0 beta
- Remove better-auth integration and all authentication-related code
- Refactor font service with provider-based architecture (Google, FontShare, Fontsource, Bunny, Google Icons)
- Add new API endpoints: CSS generation, favicon extraction, OG images, screenshots, webfonts
- Remove unused utilities: image processing, storage adapters, rate limiting, memory cache
- Simplify configuration: remove database and OAuth requirements
- Replace @funish/basis with vite-plus for build tooling
- Add Dockerfile for containerized deployment
- Update project documentation to reflect new architecture
- Move from nitropack to nitro package
- Update all dependencies to latest versions

BREAKING CHANGE: Authentication functionality has been completely removed.
All endpoints are now publicly accessible without authentication.
