Standards-unification batch 1 (CODE_STANDARDS 'Error responses', exemplar
categories.cts): inline res.status().json(standardizeError(...)) bodies and
try/catch-500 wrappers replaced with thrown ApiError factories; the terminal
handler formats 4xx and masks+logs 5xx. Wire shapes preserved, including
client-visible codes (ALREADY_MATCHED, DUPLICATE_MATCH, NOT_MATCHED,
NO_DEBTS, INVALID_PLAN_STATE, BANK_SYNC_DISABLED).
Also kills three more err.message-on-500 leaks in dataSources.cts (DB_ERROR
wrappers) that the QA-B13-02 grep missed; SimpleFIN errors keep their
deliberate sanitized pass-through via ApiError wraps (tokens/URLs stripped).
snowballPlanRoute.test.js harness now mirrors the terminal handler for
thrown errors (same wire shape as production). Server suite 252/252.

utils/logger.cts — console-compatible log.{debug,info,warn,error} with:
- level gating (LOG_LEVEL; debug in dev / info in prod), and
- REDACTION of secrets/PII (sensitive keys + bearer/JWT) so tokens,
passwords, and encrypted values never reach the logs (financial app).
Backend is abstracted (console now, swappable to pino later).
Swept all 317 server-runtime console.* across 35 files → log.* + inserted
the import at correct scope. tests/logger.test.js pins the redaction
contract (4 tests). CODE_STANDARDS updated; raw console.* is now banned in
server code.
Verified: check:server + typecheck:server + lint clean; 240/240 server
tests; client 50/50; build; e2e probe 17/17; boot smoke logs flow through
the logger and graceful shutdown intact.

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).
