Streamline emoji reactions UI

#### Is your feature request related to a problem? Please describe.
When trying to deal with emoji reactions to a message I have to consider multiple UI elements at different places.

After long-pressing a message, the popup contains the following non-contiguous UI elements regarding reactions:
* The quick-reaction emoji bar
* The Add Reaction menu item
* The View Reactions menu item

This causes an (admittedly tiny) bit of cognitive overhead due to having to read the entire UI to figure out how to add a non-quick emoji, and then adding a little extra confusion because two non-contiguous menu items have an icon that represents a reaction/emoji.

#### Describe the solution you'd like.
Ideally I'd like to have the last item on the quick-bar be a (...) indicating that I can tap that to select from the wider list of emojis, and remove the redundant "Add Reaction" menu item.

#### Describe alternatives you've considered.
Instead of removing the "add reaction" menu item it could be moved down so that the me menu item order is:
* Copy
* Quote
* Add Reaction
* View Reactions
