Add swipeable navigation

[du82]

As a user, I would like to have swipeable navigation, similar to WeChat. This makes things so much easier, so I don't have to reach for a specific button in the top left corner to go back to the previous page.

Idea: On a chat page, You can swipe L>R to go back, and R>L to open the other person's profile, or if in a group open the group info page.

Examples:

@ducheng0 thanks for raising this issue! There's a lot of opportunity for more gesture based / swipe interactions. We do need to make sure gestures don't conflict. E.g. swipe in a message in a 1:1 chat can easily be misinterpreted as swipe between nav bar items (swipe to wallet) and swipe to the other user's profile.

I think the issue would benefit from a global review of swipe actions and navigation.
