Fix defcon having wrong text when disabling.

#### Closes #539

This pull request fixes the issue for wrong status in the embed, as well as unifying certains if else to prevent similar future errors.

Most notable code is here:

```python
log_msg = f"**Staffer:** {actor} (`{actor.id}`)\n"

if change.lower() == "enabled":
    icon = Icons.defcon_enabled
    color = Colours.soft_green
    status_msg = "DEFCON enabled"
    log_msg += f"**Days:** {self.days.days}\n\n"
elif change.lower() == "disabled":
    icon = Icons.defcon_disabled
    color = Colours.soft_red
    status_msg = "DEFCON enabled"
elif change.lower() == "updated":
    icon = Icons.defcon_updated
    color = Colour.blurple()
    status_msg = "DEFCON updated"
    log_msg += f"**Days:** {self.days.days}\n\n"
```

To remedy this issue, the class will now have a private class variable

```py
_defcon_log_info: Dict[str, Tuple] = {
    'enabled': (Icons.defcon_enabled, Colours.soft_green, "**Days:** {days}\n\n"),
    'disabled': (Icons.defcon_disabled, Colours.soft_red, ""),
    'updated': (Icons.defcon_updated, Colour.blurple(), "**Days:** {days}\n\n"),
}
```

Another big change is the introduction of `_defcon_action` to unify the process all defcon actions has to go through:
- Try to do the action.
- Log error if there is any.
- Send log message.
