@programming.devDude, you're not lost. You have highly specialized requirements that the vast majority of people don't have so most people won't be able to help. But you definitely are ahead of the average Linux user here.
I'm one of the people that can't help you, but it looks like some others here have good suggestions
Is there a passkey setup that's easy to self host? I think passkeys with a backup would be best.
Scrum lends itself to procedural nonsense. It's rarely implemented in a way that improves project management.
Did you look into Raku at all? I'm fascinated with it but haven't used it for anything serious.
I've been using Podverse but I'm not sure if it meets your requirements. I just use it in the browser when I'm on Windows. The Android app doesn't seem like a web wrapper. Its source code is available under the AGPL. I've been paying $18 per year for the hosted service, but they provide instructions on self hosting.
