Don't place thread button next to video call button

The "threads" button is super close to the video call button.


I have already started many video calls by mistake in a short time, by accidentally pressing the wrong button. I am a member of several groups and it is very annoying when every group member gets notified by this.

And it's sometimes not particularly appropriate that a livestream is also immediately transmitted from you to everyone, especially if you're not expecting it.

This problem could be solved e.g. as follows
- add more margin between threads and call button, so it isn't that likely to click it by mistake
- Add confirm dialog "Do you want to start a video call now?" before the video call starts
- Move threads button down to the bottom bar, maybe next to the text input entry.
