Run computers with resources and health checks, add settings for bots, workspaces, computers and users

- Computers get CPUs and memory (default 1 CPU, 2 GB), set at creation and
  editable; new resources stop, remove and recreate the container, its home
  dir kept. Every computer container has a docker health check and stays
  "creating" until it passes; only healthy computers are reached, by
  hostname, else by their IP on the network (dev outside docker).
- Docker is required: the app creates the cobble network on startup and
  exits without docker.
- Production container: deploy/run-app-container.sh mounts .env, the data
  dir and the docker socket; the database (DB_DIR), media, computers' homes
  and bun-sqlite's live schema now live on the data volume.
- Settings pages for bots, workspaces, computers and users, sharing list
  components; bots can be deleted; users are created with a password and
  confirmation, edited and deleted through RBAC-gated APIs.
- User types trimmed to super_admin, admin, member, read_only and revoked;
  admins manage members. UserAvatar shows profile photos from the user row.
