main/maui*: update apps and plasma-angelfish

This MR updates the app to the latest commit (currently from 2 days ago). It also updates plasma-angelfish, but I changed the $pkgrel to follow the format of the other Git packages we have which causes pmbootstrap (and I guess apk too) to think the previous version is of a higher number. I'm not sure what to do about previously installed copies, but for new ones removing the old version manually from the repo should be good enough.

This also re-enables plasma-angelfish and vvave in the default Plasma Mobile installation, as they were previously disabled due to qt5-qtwebengine (which they depend on) requiring a soname bump upstream.
