feat: page password - Githubissues

Adds support for native Wordpress page passwords, will add some notes to docs and testing checks Testing page: https://bubs-next-git-122-page-password-patronage.vercel.app/flex-demo/ (pw: demo24)

[ ] Test with a bad password and you should see it return an "incorrect password" message in below the password box and that message should go away when you resubmit with the correct password.
[ ] Test with correct password and page should load all content.
[ ] When the password submission happens the button should be disabled and change to "loading" to avoid confusion of the page sitting there for a couple seconds while we validate the password/fetch the page data.
