Before this commit, chat window actions were all placed in
the right part of header. It was showing the main action (call),
close action, and all other actions in dropdown menu from
the "..." (more) button.
This commit now replaces the "..." (more) button by clicking
on avatar/name of conversation. The "..." (more) button has been
replaced to "_" (minimize/fold) button, as clicking on header to
open/fold chat window can become hard due to avatar + name being
clickable to show most chat window actions.
This commit also adds the following actions in chat window:
- Open (Employee) Profile
- Rename (conversation)
