test(cli): deflake setup-claude.test.ts — silence console to stop stdout/report interleaving (#5959) (#6019)

Integrated into release/v3.8.44. Deflakes tests/unit/cli/setup-claude.test.ts (#5959) — verified in CI: setup-claude now passes in Unit Tests fast-path (2/2).

Merged with --admin over two PRE-EXISTING base-reds proven independent of this test-only change (this PR only touches setup-claude.test.ts + CHANGELOG):
- Fast Quality Gates → check:test-discovery: tests/unit/executors/{firecrawl-fetch,xai-executor}.test.ts are orphaned on release/v3.8.44 (added by #5793/#5800); the shard glob 'tests/unit/{api,...,ui}/**' omits 'executors'. Both blobs exist on the pristine base.
- Unit Tests fast-path (2/2): tests/unit/settings-i18n-keys.test.ts → 'direct translation calls have English messages' fails on the pristine base too (unrelated i18n base-red).

 ### 📝 Maintenance
 
+- **test (deflake `setup-claude`):** `tests/unit/cli/setup-claude.test.ts` failed ~50% of runs with `Unable to deserialize cloned data due to invalid or unsupported version` at file teardown (all subtests passed), randomly reddening `Unit Tests fast-path (2/2)` / `Fast Quality Gates` across the PR→release queue. Root cause: `node --test` streams each file's report to the parent as V8-serialized frames on fd 1 (stdout), and the CLI helper under test (`syncClaudeProfilesFromModels`) prints progress via `console.log` — that stdout output interleaved with the serialized frames and corrupted the stream. The test now silences the stdout-writing `console` methods for the file's duration (no assertion inspects stdout), making it deterministic (15/15 green locally). ([#5959](https://github.com/diegosouzapw/OmniRoute/issues/5959))

 - **API validation:** add a `validatedJsonBody(request, schema)` helper in `src/shared/validation/helpers.ts` that fuses JSON body parsing and Zod validation into a single call, returning either the type-narrowed data or a ready-to-return 400 `NextResponse` with the standard error envelope. Salvaged from the closed refactor PR #5075 (Tier 1 portable helper) with a focused 6-case regression test. Co-authored-by: KooshaPari <KooshaPari@users.noreply.github.com>
