Bug: Horse, Mule and Donkey pose attribute not working

### In which plugin has the error occurred?

FancyNpcs

### What happened?

When a horse/donkey/mule npc is appearing, it is always rearing. Once you have interacted with the NPC, the rearing stops. Changing the pose attribute does not change this. Expected the npc to have the set pose.

### In which software has the error occurred?

Paper

### Plugin version

2.11.0

### Server version

26.2

### Relevant log output

```shell

```

Start by reproducing the horse, donkey, and mule NPC behavior with FancyNpcs 2.11.0 on Paper, using the configured pose attribute before and after interacting with the NPC. Trace the plugin's handling of these entity types and verify that the configured pose is applied immediately and remains effective without interaction.
