Super-productivity: [Feature Request] Archive Project in version 5

[Jackymancs4]

Hello @johannesjo ,

This issue is meant as a follow up of #104 , in order to track the efforts (or intentions) to bring back this feature.

For reference, I see here

https://github.com/johannesjo/super-productivity/blob/59e2a19f2140be6c315a2e3f41e8300fc0c9ccff/src/app/pages/project-overview-page/project-overview-page.component.html#L41-L54

that all archive-related code has been commented out, and this commit https://github.com/johannesjo/super-productivity/commit/41166e765bff4982cf46de02e3b3e04fa90f013c message says that it's most likely a temporary change.

Thanks for opening this up. I currently intent to bring back the feature. Not sure when this will happen though as there might be another big model change coming up, because I'd really like to improve syncing to make a hybrid usage with mobile more viable.
