Add a pause button to the battle commands.

### Preparation

- [x] No one has asked for this feature before in other issues (even the closed ones)

### Describe the feature

Sometimes the battle is too hard to faceroll it with the script, and I have to run the last turn manually.
Right now I have to watch the battle to stop the script at the right time. It would be more convenient if it were possible to make a script for the first two turns, so that on the third turn the Automata stops script.

The issue does not name any files or tests. Start by searching the repository for battle command execution and turn handling, then trace how the Automata stops or hands control back to the user. Done means a battle script can be configured to pause after a specified turn so the next turn can be run manually.
