2.2.1

Fixed

• PDF save directory not created before writing invoice/quote/purchase-order PDF attachments (file_put_contents: failed to open stream: No such file or directory)
• Portal routes (quotes, invoices) returning 401 — moved out of authenticated CRM middleware group into own web-only route group so signed links are publicly accessible
• Missing portal route for purchase orders (laravel-crm.portal.purchase-orders.show not defined) — added PurchaseOrderController, portal view, and routes under /p/purchase-orders
• PHPFlasher v2 API compatibility — replaced flash($msg)->success()->important() chained calls with flash()->success($msg) across all controllers (v2 no longer supports chaining type/importance methods on the returned Envelope)
• Flash notifications appearing behind the fixed-top navbar on portal pages — bumped .fl-wrapper z-index above Bootstrap's navbar in the portal layout
• Missing invoice_sent and purchase_order_sent lang keys
