Maurice 724c88c201 style: format server and shared with prettier
A mechanical prettier --write over server/src, server/tests, server/scripts
and shared/src with the workspaces' .prettierrc; nothing but layout and
import order changes, and every file keeps the same set of imports. shared
is formatted throughout and its format baseline is empty. The server
baseline keeps the 35 files that Prettier would grow past their lint:size
limit (they need a split first, which is not a formatting change), and the
generated entity files stay as their generator writes them.

/**
* The anonymous surface of the server, as a list.
*
* This is what makes default-deny durable. The APP_GUARD protects what exists
* today; this fails when a NEW route arrives that answers without a session and
* nobody wrote it down. The same shape as the body-contract gate, and for the
* same reason: a rule with no inventory behind it decays into whatever the last
* person needed to make a test pass.
