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 plugin host's job scheduler now uses the cron package (the one
@nestjs/schedule wraps), so node-cron and @types/node-cron leave the
dependency tree entirely. Verified against both real libraries that the
accepted cron grammar is identical — no plugin's declared schedule tightens —
and pinned that with an unmocked compat test.
