feat: add comprehensive OpenAPI documentation and refactor routes

- Add Swagger/OpenAPI documentation for all API endpoints (files, code, notes, folders, users)
- Refactor route files into modular folder structure (crud/actions/trash/counts)
- Fix TypeScript type inference issues with OpenAPIHono validators
- Fix route registration order to prevent /{id} catching /empty-trash
- Increase file download rate limit to 1000 req/15min in development
- Add Swagger docs link to README (https://api.typelets.com/docs)
