Per-host group gating in Caddy from X-Authentik-Groups; Discord roles -> Authentik groups policy; domain-level forward auth documented

BOT_REQUIRE_GROUP / LIVE_REQUIRE_GROUP in .env drive a header_regexp matcher after forward_auth
(403 before the app). authentik/discord-roles-to-groups.py syncs Discord roles into groups at
every login so access follows Discord roles without manual edits.
