Several pause bugs

1. Using a skill at the same time the passive or merc screen opens prevents the server from pausing
2. The merc screen seems to need to wait for info from the server before it displays the UI, but it only tells the server to pause once the UI pops up (delayed)
3. You're briefly unable to control your character after unpausing depending on your latency (client doesn't accept input until the server confirms the unpause) (also in PoE2)
