Use the runtime keyword samesite consistently for session cookies.

The session code passes same_site, but Response.set_cookie accepts samesite. When the session changes, this raises TypeError before the response is returned and no Set-Cookie header is added. Rename the call to samesite or add compatible support for same_site before marking this complete.

Make CSRF cookie security configurable.

This call omits secure, so Response.set_cookie emits a Secure cookie. Over HTTP, clients do not send that cookie on the next unsafe request. CsrfProtect then generates a new token and rejects the submitted token from the prior response.

Add a cookie_secure option that defaults to True, and pass it explicitly to set_cookie.
