Don't just check for the "YYYYMMDD" format, but also "YYYY-MM-DD"

It's happened before that Contacts showed the wrong date due to some
(implicit) time zone conversions, so let's make sure we test this.

While we're at it, extract some of the logic in parsing a single contact
birthday in a separate helper function so we don't need have too much
copy-pasta.

The gnome-online-accounts (g-o-a) build is failing in the CI due to some
missing dependency (libkeyutils) for the Fedora backend. Since the
Fedora backend doesn't actually matter for GNOME Contacts, we can just
fix the problem by not building it.

While we're at it, we can also turn off some other compile options that
aren't needed either for Contacts.

A `GdkPaintable`'s contents might change at any given time, so we need
to make sure that the crop area widget queues a redraw when the content
does change.

This allows for example paintables that originate from a video stream to
actually work.

Migrate to only using `GtkSnapshot` APIs, hopefully we can then avoid
some performance bottlenecks.

There's a chance that the paintable reports an intrinsic width or height
of zero (for example, this can happen in a GStreamer pipeline). We use
those numbers as divisors, leading to an illegal divide-by-zero.

Fix it by just returning early, since we can't really use the value
anyway.

Setting the application name in main() causes that the string remains
untranslated. Moving it to the startup phase solves the problem.
Also set a default icon for the window, which is commonly used by desktop
environments on Xorg.

It's a bit nicer to use since we don't have to return some seemingly
arbitrary boolean in the callback function, and it's immediately clear
the function is only going to get called once.

We "lost" this feature with the GTK4 port. Re-implement this again with
the camera portal and a GStreamer pipeline to handle the pipewire
buffers.

Since we use the "gtk4paintablesink" element for integrating the
GStreamer's buffers with GTK4, we need to make sure that we have the
necessary dependencies in the Flatpak manifest too (since it's written
in Rust). For now, we solve this by copying Showtime's flatpak manifest
elements.

Thanks to Jordan Petridis and Maximiliano Sandova for figuring out the
Flatpak Rust integration.

xdp_portal_new() aborts the whole program if fails. Use xdp_portal_initable_new() instead.
