build: add TypeScript configuration and generate declaration files

- Add tsconfig.json for TypeScript compilation with declaration and source map generation
- Generate .d.ts declaration files for all modules, services, controllers, and models
- Update package.json with NestJS dependencies and TypeScript development tools
- Include database files in the distribution output for persistence
