chore: remove unnecessary async and spacing

[ChiragAgg5k]

What does this PR do?

1. fix spacing in sdk for web (there was one extra in front of method names).
2. remove unnecessary async in sdk for node.
3. make the return for webAuth be string or void instead of promise. this previously did not give an error since methods were async.
4. remove unnecessary adding of payload in web auth. it would just add project in the payload, which would already be added in headers:
