Add Bazarr + Huntarr webhook notifications via Apprise jsons://

Both services now send notifications to the hookshot webhook endpoint:
- Bazarr: switched from broken Apprise Matrix URL to JSON notifier
  with jsons://matrix.lotusguild.org/webhook/<uuid>
- Huntarr: fixed apprise_url from raw https:// to jsons:// scheme

Both hookshot transforms updated to parse Apprise JSON payload:
{version, title, message, type, attachments}

Huntarr avatar set from selfhst icons CDN.
