* Avoid multiple definitions of `centerObj()`; this was very bad anyway
* Include `c++utilities/tests/testutils.h` upfront so the formatting
operators are included before CppUnit
* Set content margins to take shadow effects into account
* Fix behavior when showing the QMenu not as `Qt::Popup`
* Prevent polishing as it would wrongly override our window flags
* Use the background color from the application's palette as the
background color from the QMenu itself is changed by the Windows 11
style
* Remember new size after user resized the window
* Remember new position after user repositioned window and using explicit
coordinates has been configured in the appearance settings
This might be useful on Wayland where positioning the popup is otherwise
not possible at all. Combined with a session restoration mechanism this
might actually be a feasible workaround. The user just needed to position
the popup once wherever it is wanted to show up and then the compositor
could remember that position.
Especially the resizing would also be useful on other platforms (and is by
the way also already possible when using the Plasmoid showing it as part of
the system tray Plasmoid).
Not sure why I'm getting
```
Fehler beim Abfragen der Syncthing-Konfiguration: Error transferring http://127.0.0.1:8384/rest/system/config - server replied: Forbidden

one one of my setups but this kind of error can likely be ignored shortly
after the start similar to other types of errors.
So far the Plasmoid is not covered. It would likely not be very useful
anyways because under GNU/Linux the default icon theme can be determined
from the system and thus the "fallback" default this change is about is not
effective.
In this case the connection from the setup detection is not the correct
one. The connection used to apply the settings should generally be used for
querying the QR-code.
* Remove experimental pinning feature again and instead allow using a
normal window
* Pinning made it inconvenient to close the (frameless) window again
* Pinning required hiding/showing the window which didn't look very
nice (and setting flags directly via `QWindow` didn't work as well)
* As normal application/window positioning issues on Wayland are less
problematic (and those aren't going to be fixed any time soon, if at all)
* Allow using icons from freedesktop.org icon theme for most ForkAwesome
icons if available
* Let's not use it for the nested list of details in the models for now
* See https://github.com/Martchus/syncthingtray/issues/121
