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).

The tracker aggregation core (getTracker, safe-to-spend, bank tracking,
overdue count). Aggregation-heavy so money helpers are plain-required (any)
to avoid Dollars|null arithmetic friction, matching analyticsService.
Behavior-preserving. Verified: typecheck:server 0, check:server 0, suite 226/226.

routes/tracker.js had no try/catch and returned a plain {error} shape; the
three GET handlers now wrap in try/catch + standardizeError (including the
invalid-month path). applyAutopaySuggestions ran INSERT + applyBalanceDelta
as two un-transactional steps on a GET — wrapped both in one db.transaction.
Tests: autopay creates one payment + drops balance (idempotent), route
returns standardized error.

- Batch queries replace per-bill loops in tracker and analytics
- monthly_bill_state, payments, prev month payments batched with WHERE IN
- Empty billIds guards prevent SQL errors
- Hudson security audit: 5/5 PASS (SQL injection, empty IN, user scoping, data leakage, type safety)
- Backend: previous month calculation with year wrapping (Jan→Dec)
- Backend: previous_month_paid per bill row, previous_month_total in summary
- Frontend: 'Last Month' column in desktop table with muted text
- Frontend: 'Last Month' in mobile view, summary card for prev month total
- Hudson security audit: 5/5 PASS (SQL injection, date wrapping, user scoping, auth, XSS)
