Revival page to "get" Strava authorization from users

I've developed on deprecated version [some endpoints]((https://github.com/vyper/biketastic/blob/deprecated/functions/src/modules/oauth.ts)) to orchestry oauth with Strava and [page](https://github.com/vyper/biketastic/tree/deprecated/public) (on hosting) to show "login", maybe this a way to try again and get more authorizations for tests.
