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.

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 four plan-lifecycle routes (pause/resume/complete/abandon) were near
-duplicate copies returning a plain {error} shape; folded into one
transitionPlan(req,res,{allowedFrom,setSql,action,past}) helper that returns
standardizeError {message, code}, keeps the state guards and ownership scoping.
- Standardized the remaining plan endpoints' error responses (start/list/active/
patch) to standardizeError too.
- enrichPlanWithProgress fetched each snapshot bill one-by-one and wasn't user
-scoped; now a single WHERE id IN (…) AND user_id = ? batch.
Test: tests/snowballPlanRoute.test.js (transitions, INVALID_PLAN_STATE guard,
ownership 404, dollar-denominated current_debts). Server 154 pass.
