Grand Pine App

Add employee time-clock and loyalty program features Implement employee self-service time-clock (check-in/check-out), manager-side time log management with approval workflows, and payroll calculation methods (Generous/Hourly). Add customer loyalty program with point tracking, VIP scoring, and redemption at checkout. Includes work sheet PDF generation, batch employee operations, per-customer detail views with stats, and in-app selling price/description editing for items. Adds gp_employee_self, get_customer_sales_stats, and GP Time Log server scripts, along with new DocTypes for time logs and pay adjustments. Introduce cash register functionality and wide-ranging server/client features: add GP Cash Session & GP Cash Adjustment doctypes, Cash Register page, open/close/adjust flows and server APIs to fetch cash sales and adjustments. Implement returns/refunds flows: sales returns (credit notes), purchase returns (debit notes), and journal entry reversal APIs + UI actions (invoice refunds, receipt returns, reservation/pool refunds, expense reversal). Add receipts-by-item search, item sales stats, license status API and client-side trial-lock handling (trial-ended screen, license banners, and disabled-user detection). Improve ERPNextService: bootstrap-scope breaker override, circuit-breaker handling, image URL re-resolve, caching fixes, bulk queries for pool/customer data, enhanced receipts pagination and scoped queries. UI/workflow updates: receipts, invoices, customer detail, expense/receipt pages, subscription and pool dialogs, stock reorder hints, ticket page cash-register icon (toggleable), settings and user settings persisted toggle, and minor layout/UX fixes. Bump app version to 1.6.16+1. Broad intent: complete backlog items (refunds/returns/cash register/receipt search), improve robustness on fresh servers and present clear trial lock UX.
