Redeploy Fly.io App to gcal.fly.dev

[nelsonic]

At present the app is deployed to: https://dwyl-calendar.fly.dev

The working App has not yet been deployed.

And it does not yet have any of the necessary Google Auth API keys:
https://fly.io/apps/dwyl-calendar/secrets

So I want to use this opportunity to:

• Create a New Fly.io App with the name cal under the dwyl-calendar org so that we can reuse the existing DB. Currently: https://cal.fly.dev/
  

• Deploy the gcal App and comment in this issue with progress. 💬

• @nelsonic to setup Google API Keys (for maintenance reasons...)

• Finally DELETE the existing "placeholder" App named dwyl-calendar once we confirm cal.fly.dev is working.

  Note: I'd much rather just rename it but it's not supported see: https://community.fly.io/t/how-to-rename-my-apps/3098

We are going to be using this calendar App internally so we need to make it good.
And we will be abstracting some of the code into a library very soon to tidy up.
Watch this space: https://github.com/dwyl/gcal

apparently the cal.fly.dev app name is taken:

But when you attempt to visit https://cal.fly.dev/ it times-out. so 🤷‍♂️

So went with https://fly.io/apps/gcal 👌

Apparently it can take a few hours to be updated ...
