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 coverage ratchet caught something worth keeping: an inline
`(a, b) => (a < b ? -1 : a > b ? 1 : 0)` is a new function with four branches at
every call site, and two of the three in src/nest/common sit on error paths that
a passing test never walks. Three restatements of the default sort order were
enough to pull the domain under its pinned thresholds (functions 97.8% against
99, branches 87.92% against 89).
Writing tests to walk those error paths would have been solving the wrong
problem. byCodeUnit says the same thing once, is covered once, and the callers
read better for it.
Its test asserts equality with a bare `.sort()` rather than hand-written
expectations, since "identical to the default order" is the whole contract. It
also pins what byCodeUnit is NOT: `['Zelt', 'Übernachtung']` keeps that order,
where localeCompare swaps it — so the next person reaching for a comparator on a
list a human reads picks the other one.
