fix: resolve pre-release audit blockers across settings, auth, printing, and UI - #1546
Issue / Discussion: Pre-release audit follow-up for candidate 67b457ff (addressing findings from #1488, #1524, #1525, #1530, #1540, #1542, #1545)
Summary
Fixes all three P1 release blockers, the flaky scheduled-order browser assertion, and the three UI/printing findings identified in the pre-release audit:
Added GET /api/settings/printing gated on printers.manage or settings.view in main/routes/settings.ts.
Migrated Settings' Receipts & Printers hydration (frontend/src/app/(dashboard)/settings/page.tsx, frontend/src/lib/print-language-policies.ts) to GET /api/settings/printing, gating bill-templates / business / KDS+KOT auxiliary reads by their own permissions with printingPayload fallbacks so printer specialists (printers.manage without settings.view / bills.* / print-templates.view) hydrate real server state without clobbering unrelated flags.
Required printingHydrated && !printingHydrationFailed on PrintersSettingsTab editing controls and printingHydratedRef on savePrinting / printingDirty, showing printing-hydration-error when reading fails.
Extracted shared authenticatePinLogin in main/routes/auth.ts and migrated POS (:3001), standalone KDS (:3002), and standalone Server App (:3003) PIN sign-in handlers to revalidate the active user, matching pin_hash, and surface authorization synchronously right at the JWT issuance boundary after async PIN verification.
Added the corresponding post-bcrypt.compare active/hash revalidation guard to POS POST /api/auth/login.
Added transactional isSessionLiveAtCommit verification at the compare-and-set commit boundary in handlePasswordChange and handlePinChange (main/routes/auth.ts), plus an initial lock-entry check in handlePinChange, so sessions revoked via logout during bcrypt.hash fail with 401 and issue no replacement token.
Added clearLocalSession(expectedToken?) to frontend/src/store/auth.ts and onSessionCleared / onSessionTokenReplaced callbacks to useKdsConnection, wired exclusively on dashboard /kds (frontend/src/app/(dashboard)/kds/page.tsx) while leaving /kds-standalone isolated.
Replaced the wrapping dot container in frontend/src/app/customer-display/page.tsx with a single-row h-2 non-wrapping container capped to a 7-dot sliding window centered on activePageIndex while retaining the numeric page counter (activePageIndex + 1 / totalPages) and overflow badge.
Aligned customer receipt large order number banners in frontend/src/lib/printer/web-print.ts, frontend/src/lib/printer/receipt-encoder.ts, frontend/src/lib/printer/tax-bill-encoder.ts, main/printers/document-classic.ts, and main/printers/document-compact.ts with KOT's #<number> convention (removing hardcoded English ORDER #).
Updated frontend/e2e/scheduled-orders.spec.ts Scenarios A, B, and C to wait on waitForRequest and requestfailed for each aborted POST /api/orders attempt and match the unconfirmed-order status toast before asserting request counts and idempotency keys.
Scope
Preserves the #1537 decision leaving manual pickup controls for KDS-disabled stores deferred post-release (#1523).
Standalone /kds-standalone and /server-standalone auth isolation remain unchanged.
All lint, format, typecheck, build, docs, and i18n checks passed (exit 0).
Compatibility & data safety
Database/data impact: None - reads/writes existing settings and users columns.
Migration: None.
User-visible behavior: Customer receipts render #<number> instead of ORDER #<number>; customer display caps visible page dots at 7 on a single row; dashboard KDS logout clears shared POS dashboard session state; printer specialists preserve existing receipt toggles when editing printing settings and see disabled controls on read failure.
Offline/network impact: None - all changes remain offline-first.

Walkthrough
This PR consolidates printing-settings reads, updates printing-option hydration and access controls, and changes receipt order-number banners. It also changes PIN and session handling, limits customer-display pagination dots, and consolidates scheduled-order E2E assertions.
Adds GET /printing with printers.manage or settings.view access. The response includes printing options and parsed language policies. Tests cover defaults, authorization, and unauthenticated access.
Settings hydration and editing frontend/src/app/(dashboard)/settings/page.tsx, frontend/src/components/settings/PrintersSettingsTab.tsx, frontend/src/lib/print-language-policies.ts, frontend/e2e/settings-rbac-readonly-nav.spec.ts, frontend/e2e/settings-request-budget.spec.ts
The settings page reads printing options from one response and tracks hydration by tenant. Printer controls require completed, successful hydration. E2E tests cover scoped printer access, failed hydration, and request behavior.
Adds shared PIN authentication and uses it in POS, KDS, and Server App login routes. Login rechecks the active user and PIN hash before token issuance. Race tests cover PIN changes and account deactivation during verification.
Credential updates and session checks main/routes/auth.ts, tests/self-service-credentials.test.ts
Password and PIN changes check session validity during updates and distinguish invalid sessions from concurrent conflicts. Tests cover logout during credential hashing.
KDS session callbacks synchronize clearing and token replacement with the shared auth store. Token-aware clearing preserves a newer session when an older logout completes.
Receipt order-number banners
Layer / File(s)
Summary
Banner rendering and expectations main/printers/document-*.ts, frontend/src/lib/printer/*, tests/print-document.test.ts
Receipt and kitchen-ticket banners now show #<number> instead of ORDER #<number>. Tests cover backend and frontend renderers, language variants, RTL output, and paper width.
The documentation describes the number-sign format for customer receipts and kitchen tickets.
Customer-display pagination
Layer / File(s)
Summary
Pagination window and layout validation frontend/src/app/customer-display/page.tsx, frontend/e2e/layout-integrity.spec.ts
The indicator shows up to seven dots in a non-wrapping window around the active page. The E2E test checks layout at a 550-order feed and after page rotation.

FreeOpenSourcePOS/FloCafe#1545 — That PR added large order-number banners; this PR changes their displayed prefix and updates related documentation and tests.
Merge Risk: Minimal · previous review 4d819
This change adds a permission-gated printing-settings read, tightens PIN and session handling, and updates receipt banners and the customer-display pagination. No merge-blocking issues remain. The one open item is a documentation note on nullable response fields in the API reference.

Credential changes stop when the session is no longer live.
Printer specialists can load printing settings without broad settings access.
Dashboard KDS logout and token changes update the shared POS session.
The customer display keeps its page dots in a single row of at most seven.
Customer receipt banners show # before the order number.
Scheduled-order checks wait for aborted requests before counting attempts.
khaira777 explicitly leaves manual pickup controls for KDS-disabled stores deferred until after release; that acknowledged limitation is not reported here.
Review used source and test inspection. Tests, builds, and visual captures were not run.
