Makes curator inventory update when buttons are pressed. (#87841)

## About The Pull Request
Adds two calls for `update_static_data_for_all_viewers()` so the UI will
update when a player switches pages or removes an item in the inventory
screen.
## Why It's Good For The Game
Responsive UI good. When I click button UI should respond accordingly. 
fix #82733
