Rename signIn from useAuthActions to authorize

[IAlphaOmegaI]

signIn does make sense in most cases, but when implementing your own auth mechanism, or using a more traditional email password auth with resend, signIn("sign-up", ...) makes for a very bad time maintaining and reading.

I propose the name authorize or authenticate which is more encompassing and offers better readability for the future.

So TLDR from:

const { signIn } = useAuthActions() 

to

const { authorize } = useAuthActions()
