Synaplan 4.0 AI Tamer Release

Big Steps

Added Fable 5 back and welcomed Sol, Terra and Luna. Displaying a token taxameter showing your spendings. Integrated Nextcloud further (look for synaplan in their App store) and confirmed the backend for the Outlook Plugin:

https://github.com/metadist/Synamail

You may install that into Outlook and kick-out the Copilot for some tasks.

Mobile is prepped now. I hope we can release the mobile app before the summer holiday starts.
