refactor: update import statements to use .js extensions

- Changed all import statements across the project to include the .js extension for consistency and to comply with ES module standards.
- Updated imports in various files including bootstrap.ts, shutdown.ts, config.ts, and many others.
- Ensured that all related modules and types are correctly imported with the new extension.
