Add WEBHOOK_SECRET env var for authenticating incoming Owncast webhooks
via a ?secret= query parameter. Requests with a missing or incorrect
secret are rejected with 401. If unset, all requests are accepted
(with a startup warning).
Also includes previously uncommitted work:
- IRC server password support (IRC_PASSWORD env var, PASS command)
- IRC username/ident field in config
- IRC_PASSWORD and SELinux volume flag in docker-compose.yml
