mobieusChat admin (chat rooms) has no mobieusKnow article — and live_chat is default-on for every tier

Area: Admin plane (audit p12) · Surface: /admin/chat-rooms (AdminChatRoomController) · Dimension: documentation · Severity: major

mobieusChat is enabled by default on every tenant tier, but there is no mobieusKnow article documenting the admin surface (creating/updating/archiving rooms, muting/unmuting users, uploading custom emoji, suggest-topic). No chat article of any kind exists in the wiki index. Tenant admins running a default-on feature have zero documentation for how to manage it.

Evidence

Live wiki index is authoritative (controller redirects /know -> /know/index; KnowledgeController::index lists all pages, no admin-feature pagination). curl of /know/index (HTTP 200, 78619 bytes) enumerates all 71 articles; grep for any chat article returns nothing: `grep -oiE '/know/[a-z0-9-]*chat[a-z0-9-]*' know_index_L.html` => (empty). Direct probes: `curl /know/chat-rooms` => HTTP 404, `curl /know/live-chat` => HTTP 404. Feature is shippable and ON by default: FeatureCatalog.php:130 `'live_chat' => ['label' => 'mobieusChat', ... 'default' => true ... 'Available on every tier; ungated by plan.']`. AdminChatRoomController gates on `features->require('live_chat')` then `requireRole(4)` and renders admin/chat-rooms/index (createRoom, archiveRoom, muteUser, uploadEmoji, etc.).

Suggested fix. Author /know/chat-rooms (or /know/mobieuschat-admin) covering room creation, per-forum vs tenant-wide rooms, moderation (mute/unmute/remove), custom emoji upload, and the AI suggest-topic helper; link it from the Admin & Configuration and Community sections of /know/index.
