trigger command does not fire abilities

[Bradymck]

Problem

`openhome trigger "magic 8 ball" --agent 241668` sends the phrase but the ability never runs. The agent just replies with a generic greeting instead.

This happens with all abilities, all trigger phrases.

Expected

The ability runs. The response is from the ability.

Actual

```
{"response": "Oh hey! How's it going? What brings you here today?"}
```

Also needed — assign is broken

`openhome assign` does not work from the CLI. The server returns:

```
Not allowed to edit this personality.
```

There is no way to assign abilities to an agent from the CLI. You have to use the dashboard.

Both need to be fixed for the CLI to work end to end.
