Use the same service/version type in `init()` and `startView()`

[BenoitZugmeyer]

Motivation

There is no reason why we shouldn't accept different types there. See https://github.com/DataDog/browser-sdk/pull/2781#issuecomment-2150324514

Changes

Change types, convert falsy values to undefined

Testing

• [x] Local
• [x] Staging
• [x] Unit
• [ ] End to end
