test(batch): add integration tests + sanitization asserts + coverage gap fillers (F9)

- Add tests/unit/batches-f9-helpers.test.ts (19 tests, top-level for c8 coverage gate)
  covering uncovered branches: alias-match pricing, blank CSV rows, body.input/prompt paths,
  non-object JSON lines, invalid Anthropic params, body-is-array validation
- Add tests/unit/dashboard/batch/concept-cards.test.tsx (16 tests)
  covering BatchConceptCard + FilesConceptCard: render, toggle, localStorage hydration, sanitization
- Add tests/unit/dashboard/batch/list-regression.test.tsx (15 tests)
  covering BatchListTab + FilesListTab: render N items, Remove-completed flow,
  status/purpose filter, loading/empty states, sanitization
- Add tests/unit/dashboard/batch/sanitization.test.tsx (8 tests)
  covering NewBatchWizard + UploadFileModal + useBatchActions: each error path
  asserts zero stack-trace/path leakage into the UI (D14 / Hard Rule #12)
- Fix bug in validateJsonl.ts: body=array was not caught as invalid
  (typeof array === "object" is true — add Array.isArray guard, 1-line fix)

Local src/lib/batches/ coverage: 100% stmts / 93.7% branches / 100% funcs / 100% lines.
Global coverage gate: 75.96% stmts / 71.97% branches / 75.52% funcs (all above 75/75/75/70).

/**
* F9 — Batch helpers coverage gate (top-level, picked up by c8 test:coverage).
*
* Re-exercises the four new pure helpers in src/lib/batches/ with additional
* cases targeting uncovered branches found in local coverage analysis:
*
* costEstimator.ts : alias-match (case-insensitive) path in getPrice()
* csvToJsonl.ts : blank-row skip branch; body.input/body.prompt paths
* validateJsonl.ts : non-object JSON line; invalid params field; body not object
* retryFailed.ts : whitespace-only inputJsonl; all three skipped categories
*
* The file at tests/unit/lib/batches/ runs via node --test directly;
* this file runs via the c8 coverage gate (tests/unit/*.test.ts glob) so that
* src/lib/batches/** is counted in the global coverage report.
*
* D14 compliance: all helpers are pure — no fetch, no DB, no sanitization needed.

/**
* F9 — Sanitization assertion tests for all batch components that perform fetch().
*
* D14 requirement: EVERY component that does a fetch() and shows an error to the
* user MUST NOT leak raw err.stack, err.message, file paths, or stack frames.
*
* Components under test:
* - NewBatchWizard (file upload 500 + batch create 500 + network throw)
* - UploadFileModal (upload 500 + network throw)
* - useBatchActions (cancel 500 + retry 500 + network throw)
*
* Each test simulates an error condition that would expose a stack trace
* if the component violated Hard Rule #12, then asserts the displayed error
* is an i18n key or short user message — never a raw path/trace.
*
* STACK_PATTERNS: compiled regex set for reuse across all assertions.
