Dropped @ts-nocheck from admin/payments/monthly-starting-amounts/
subscriptions/authOidc/calendar/export (~113 errors). Mostly mechanical
(catch bindings, params, never[] arrays), but the checker earned its keep:
- types/http.d.ts: added the 4-arg res.download(path, name, options, cb)
overload — the v0.42.0 root-option download fix (admin backup + user-db
export) didn't type-check against the old 3-arg-only signature.
- routes/calendar.cts: deleted dead clampDay() (zero callers; was also a
standing lint warning).
@ts-nocheck server count: 21 -> 14. Server suite 252/252.

Every routes/*.js → .cts, with handler signatures typed against the shared
http Req/Res/Next types. Routes carry @ts-nocheck for now — they're thin glue
over the (fully typed) services, so full route-level type-checking is deferred;
the handler-param typing is a head-start. server.js + test requires updated to
the explicit .cts paths.
Behavior-preserving. Verified: check:server 0, typecheck:server 0, suite 226/226,
real boot → /api/health + /api/about 200 (all routes mount).
