fix: resolve TS build errors - missing schema fields, types, and packages

- Add mustChangePassword field to User model in schema.prisma
- Add latitude/longitude fields to Client model (matching existing migration)
- Remove @nestjs/serve-static import from app.module (not in dependencies)
- Add @types/multer to devDependencies and type multer config explicitly
- Create migration for mustChangePassword column
