I suggest Vikunja. There isn't a mobile app to my knowledge, but the web UI on mobile and desktop is very responsive. It should cover the rest of the items on your list
If you're looking for a companion app, you might want to try KDE Connect. You can pair the mobile app to your Steam Deck to allow for keyboard/mouse remote input and a bunch of other cool features. There's also a Decky plugin for KDE Connect in Gamescope.
