Sign in page title typos and suggestions

[su-iCode]

• Title says "Signin", it should be "Sign in" (reference google sign in page)
• "Email or Phone number" should be either "Email or phone number" or "Email or Phone Number" (camel case or sentence case) (e.g. Google Sign in page has "Email or phone"

Looks like all sign in related pages have same html title: "Signin". Title should be changed to show corresponding intent.

• forgotPassword page title
• confirmForgotPassword title
