refactor: migrate scripts from .mjs to .ts

Converts Node.js script files from .mjs to TypeScript:
- Updates package.json script commands to use .ts extension
- Removes legacy .mjs files (cf-dns, colo, monitor)
- Scripts functionality remains unchanged
- Prepares codebase for improved type safety and maintainability

Files will be recreated with TypeScript equivalents in a follow-up commit.
