ipsec: T7545: Fix show vpn debug peer

Fix re for searching of peers in /etc/swanctl/swanctl.conf

```
search = rf'^[\s]*(peer_{peer}_(tunnel_[\d]+|vti)).*'
```

Changed to

```
search = rf'^[\s]*({peer}-(tunnel-[\d]+|vti))[\s]*{{'
```

Added message

```
print(f'\n### {command} ###')
```

so that output is not empty when `/usr/sbin/ipsec statusall`
shows nothing
