Add "I understand cobble is in development" confirmation dialog on first run

[lavglaab]

After recent announcements, we've had an influx of new people trying out cobble, not all of whom have gotten the speech about the app's current early state. I propose we add a dialog on the first run (or subsequent updates) that explicitly spells out "In this dev build, features will be missing, incomplete, and/or unstable" and requires the user to type their confirmation before proceeding.

• Figma design for the layout and text of the confirmation dialog (@lavglaab ) - see https://www.figma.com/design/mXl0svBSnlGV2MKfTj8H7e/Rebble-App%2FCobble-Layouts-and-Prototype?node-id=7388-7299&t=bY826x61UibTbTGP-4
• Implement confirmation dialog into Flutter and/or KMP

The idea is similar to Github's dangerous action confirmations: that new users will have to actually read the dialog and type out their answer into a text box to use cobble, instead of just clicking OK and moving on

I'm calling the UI done

This nag dialog shows when you launch the app after installing or updating. It cannot be dismissed, except by entering “i understand” into the text box, which will reveal the button to continue.

Is there a possibility to do a checkbox instead?

Or at least only have to type it once, and we wouldn't have to type it again after the fact?

As someone who has had to deal with end users, writing it out might stop some people from not understanding that this is made by volunteers...
