refactor: use quietDeps instead of silenceDeprecations

As suggested by Julusian in PR review, quietDeps is better because:
- It hides ALL warnings from dependencies (not just specific types)
- It still shows warnings from our own code
- This prevents us from accidentally adding deprecated features to our code
  without being warned
