Batch of low-blast-radius modules: utils/apiError, and services statusRuntime,
loginFingerprint, auditService, transactionMatchState, updateCheckService,
advisoryFilterService, bankSyncConfigService.
- types/http.d.ts: shared permissive Express-ish Req/Res/Next/Router types
(@types/express isn't installed; handlers are dynamic) — for apiError's
errorHandler now and the routes/middleware batches next.
- Every require of a migrated module updated to the explicit .cts extension.
- Confirmed + documented the Node rule: a .cts needs at least one `import`
statement or type-stripping never activates (node --check fails on the first
type token); import-less modules lead with an `import type`.
Behavior-preserving. Verified: typecheck:server 0, check:server 0, suite 226/226.
