Documentation: Disambiguate SDK methods

[knackstedt]

Description

There is insufficient explanation where a developer should use create versus insert or live versus subscribeLive. Please add a paragraph that disambiguates when and why a developer should pick one over the other in the documentation -- as it stands now it's unclear when a developer should pick one over the other. It's somewhat more clear for subscribeLive but it's still decently blurry to the unfamiliar developer -- adding a "use case" section would make it more clear where and when to use it.

Notably, there are differences in functionality where db.insert throws an error if provided a RecordId object, and db.create handles that with no error.
