Share one crew across the install, keep user memory per user

Bots, workspaces and computers now belong to the install. Users reach
workers only through bot_users (assigned by a super admin or admin) and
workspace_users; the coordinator and main computer are one per install,
and only the super admin sees the coordinator. Conversations are per
user (bot_sessions.user_id), jobs run for the session's user, and live
updates go only to who should see them.

A bot's core memory is now general knowledge shared by every user it
works for; what it learns about a user lives in bot_user_memories.

One-off scripts move existing installs over: move-bot-memory-to-owners
(run first), then share-crew.
