Fix the reply an edit text being shown in all chat rooms when multiple windows are open. This is done by changing chatBoxHelper from a singleton to being instantiated for each instance of roompage.
BUG: 454963
Since the preparation for encrypted events landed, audio playback was broken since QtMultimedia (gstreamer)
doesn't use our custom QNAM. Instead of letting QtMultimedia download the media, we thus need to manually download it
and point QML Audio to the local file. On the positive side, this also allows encrypted Audio files to be played and enables us to seek in the audio delegate :)
It does however mean that we do need to do an annoying bit of manual state management.

https://bugreports.qt.io/browse/QTBUG-83890 has been open for years with
a patch that's been stalled for years. There's no indication that it's
going to be fixed anytime soon, and it generates bug reports for us.
Let's add the typical hackaround for all non-horizontally-scrollable
scrollviews.
BUG: 457584
When hovering over a link without a target, qt5 will report the link target to be "1", which is wrong.
To work around this, we manually check if the link is "1" and if it is, we discard it.
In theory, this means that we won't get a preview for any link that actually *is* "1", but why would any link be "1"?
It's not worth reporting this to Qt since it seems fixed in Qt6
BUG: 456877
Implement showing a long datetime as a tooltip when hovering over the timestamp for a message. The timestamp is also moved to just after the username of the poster this means it will not be under the hover buttons unless the message is very short.
Also some cleanup of the alignment of items in the bubble. The reply text is now indented the same amount as the username and message and the padding isn't removed from the username and message when avatars are disabled.
Implements: network/neochat#223
QDesktopServices::openUrl does not have XDG activation support yet so it can't raise an existing browser window when opening URLs
Instead use KIO::OpenUrlJob, which does support that
In compact mode with userMessagesOnRight, the user
avatar disappeared and their messages left space
on the right for an avatar that wasn't displayed
anymore.
