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.

/**
* SCHED-GATE — the no-timers-in-the-harness regression test. buildApp() is
* shared with every integration/e2e suite, and job providers register their
* crons from onApplicationBootstrap, which app.init() fires on every boot.
* This proves the CronRegistrarService NODE_ENV=test gate holds: a full
* harness boot registers zero cron jobs, intervals or timeouts, and closing
* the app leaves nothing behind. If this ever goes red, some job bypassed the
* registrar (or used a @Cron decorator) and every suite is now running real
* timers.
