This makes the standalone KCM dialog consistent with the same KCM
when launched via kcmshell, systemsettings, or even other modules.
The dialog is required so it doesn't need to depend on kde-cli-tools.
## Summary
I've added a call to [`dialog->raise()`](https://doc.qt.io/qt-5/qwindow.html#raise) when launching the configuration dialog.
This is intended to fix a MacOS bug where the configuration window launches behind other open windows, but this call shouldn't harm operating systems as well.
BUG: 416050
## Test Plan
### Before:
Configuration dialog launches behind other open windows on MacOS.
### After:
Configuration dialog launches over other open windows on MacOS.
- Move the device combobox to the global drawer
- Move search field and new button to header
- Use Kirigami SearchField instead
- Don't switch focus away from search field when typing
- Give the New button an icon
- Clarify the search field text
- Center messages view loading indicator
- Make send and attach buttons stick to bottom of text area
- Make cursor an I-beam when hovering over text area
- Move send button to the right
- Give proper padding to messages view top
- Move refresh action to global drawer
- Show refresh button directly in loading message where it is most useful

* Instead of using the kcm to signify kde connect, just call it kde
org.kde.kdeconnect. org.kde.kdeconnect.kcm.desktop didn't exist anyway.
* Specify launchables for optimal integration in software centers.
* Specify which dbus service it's offering, in case it ever is
necessary.
* Specify the oars, stating there's no offensive content of any kind
offered through KDE Connect.
Pairing is the result of explicit user action and requires interaction
Otherwise there is no visual feedback for a pairing attempt, leaving the user wondering why nothing happens
Visually a new scrollbar is now displayed and in terms of behavior
changes the scrolling is now consistent with the other plasmoid.
This KCM will have to get installed installed in the new plasma namespace eventually.
But considering that this app is part of the release service, we should not
depend on changes in a not yet released Plasma version.

Default margins are non-zero for widgets/layouts. Thus, nested widgets
are gonna shrink further and further inward for no good reason.
This patch makes left column of this KCM (the host name, devices list
view and a Refresh button) visually aligned with the QGroupBox on the
right.
