## Summary
Upgrade the SMS App to handle multitarget addresses in the "addresses" field of a message and drop usage of the "address" field
Also note that this has all the commits from https://invent.kde.org/kde/kdeconnect-kde/merge_requests/97, but I will rebase those away once that patch is landed
Bonus: Image composition for multitarget conversations
## Test Plan
- Apply Android-side patch https://invent.kde.org/kde/kdeconnect-android/merge_requests/80
- Launch SMS App
- Notice that you can see all the recipients of multitarget messages. (Replying still not supported, but might get implemented as part of fixing replying to single-target messages)
## Summary
Desktop companion to https://invent.kde.org/kde/kdeconnect-android/merge_requests/78
Give desktop SMS app a basic understanding of the MMSes coming from Android:
- Show a fake body if we get an attachment we can't display (for now, any attachment)
- Display a fake contact header for multi-target messages since Android does not yet export multi-target address information
- Disable attempting to reply to multi-target messages
BUG: 398889
## Test Plan
### Before:
MMS messages were silently dropped, meaning:
- Group MMS conversations were not visible
- Single-target conversations with the most-recent message an MMS were not visible
### After:
- Install https://invent.kde.org/kde/kdeconnect-android/merge_requests/78
- Multi-target conversations are displayed (kind of ugly, since they have no contact information
- Single-target conversations which end with an MMS are displayed
- Plain-text MMS is displayed nicely
- MMS attachments don't show
- MMS which are only an attachment with no body are displayed with a dummy body
