bus, cli, webui: every message to the human, read state, Messages page (#1588)

Row 94, round 2. Rocko built it, Dewey approved it (comment 28104) on
manifest 53b01ea9 (16 paths, base e918a915). The bus keeps a messages
view with read state, where delivered but not read stays read:false. The
CLI gains messages and follow, and inbox leaves out messages already
read while inbox --json stays byte-compatible. The Console gets a
Messages page and an unread count in the nav. Mos gave the go under
decision 123 (public/ files). Sage gate on 645489e4 plus the patch,
12:52:14Z to 12:55:44Z: bus 115, cli 129, webui 104, all fail 0. Every
scripts/test-*.sh exited 0 (auth 15, conductor 17, config 24, discord
66, extension-package 18, foundation 44, queue 27, release 14, task 98).
Manifest 16/16 before and after.
