test: add comprehensive tests for all new features + test plan

Parser extraction: - Move parseSheet/parseWorkbook/cellStr/cellNum to lib/po-import-parser.ts so they can be unit-tested without HTTP overhead - Route now re-exports types and delegates to the lib Unit tests (165 total, all passing): - permissions.test.ts: +15 cases covering MANAGER create_po/submit_po/ manage_vendors, ACCOUNTS manage_vendors, AUDITOR all-denied, ADMIN operational denial, SUPERUSER no manage_vendors - po-state-machine.test.ts: +12 cases covering MANAGER submit from DRAFT and EDITS_REQUESTED, ACCOUNTS provide_vendor_id, AUDITOR/ADMIN denied on all transitions - po-import-parser.test.ts (new, 32 cases): cellStr/cellNum edge cases; parseSheet against real Sample_PO.xlsx (1 line item, correct values, T&C not included, vendor/quotation/T&C extraction); synthetic sheet edge cases (GST normalisation, INSTRUCTIONS stop, zero-price skip, empty rows); parseWorkbook happy path and empty-workbook Integration tests (new files): - discard-po.test.ts: owner/MANAGER/SUPERUSER can discard; ACCOUNTS and non-owners denied; status guard blocks non-DRAFT; cascade cleanup of POActions and POLineItems verified in DB - vendor-approval.test.ts: approval blocked without vendor; approval succeeds with vendor; ACCOUNTS can provideVendorId; unverified vendor rejected; AUDITOR denied; wrong-status denied - manager-po-creation.test.ts: MANAGER creates DRAFT and submits; stores correct submitterId; can discard own draft; ACCOUNTS denied; unauth returns Unauthorized - products-search.test.ts: 401 unauth; min-length validation; search by name/code/description; case-insensitive; max 10 results; lastPrice as number; inactive products excluded - import-api.test.ts: 401 unauth; 403 for TECHNICAL and ACCOUNTS; 400 no file; 400 invalid binary; 200 for MANAGER with Sample_PO.xlsx; correct line item values; T&C absent from results; vendor/PI extracted Spec/TEST_PLAN.md (new): - Testing strategy, stack, and environment setup - Coverage matrix across unit/integration/E2E layers - Permission test matrix for all 7 roles × 15 operations - Feature-level scenario index (F-01 through F-06) with IDs mapping to test files - Known gaps and out-of-scope items - Authoring conventions (PREFIX isolation, negative-first, no any) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
