v1.5.6 — transaction hardening + printer fix

v1.5.6 — Enterprise-grade transaction hardening + printer format fix

Data integrity

• Every multi-statement mutation (order creation, order item add/cancel/restore, order status, bill generate/payment/discount, addon group create/delete) now runs inside an atomic SQLite transaction via a new withTxn() helper. No more partial writes if the process dies mid-flight.
• Startup now runs PRAGMA integrity_check + PRAGMA foreign_key_check and logs any violations.
• Self-healing auto-repair for a pre-fix bills.payment_details corruption where payment JSON was stored as {A},{A} instead of [A]. Idempotent, only fixes rows whose math still balances.
• Added busy_timeout=5000 and synchronous=NORMAL pragmas — concurrent KDS writes no longer throw SQLITE_BUSY.
• On final payment, lingering pending/preparing/ready order_items are bulk-closed to served to prevent the "completed order with stuck KDS items" split-brain.

Printer

• Fixed column alignment bug in all three receipt templates (compact, classic, detailed) where product name wasn't padded to its column width, producing mangled output like Cheeseburger2 5% ₹540.00. Now reads cleanly on both 58mm and 80mm paper.
• Refactored receipt rendering to shared itemHeader / itemRow / addonRow helpers.

Misc fixes

• Removed the dropAllTables() footgun (violated AGENTS.md rule #1).
• DevTools no longer opens automatically for packaged end users (gated behind isDev).
• Backup _flo_meta.app_version now stores the real app version instead of the schema version.
• README download filenames / latest-version synced.
• Fixed build:all script name in README (was build:all-platforms).

Tests

• npm test runs backup + printer + db-audit suites.
• npm run test:printer -- --live sends a real test page to your default printer.
• npm run test:db-audit walks PK/FK/orphans/JSON/math sanity.
• npm run repair:payments -- --apply one-time repair for the legacy payment_details bug (auto-runs on app startup too).
• Tests use Node 22.5+ built-in node:sqlite so they run without rebuilding better-sqlite3 against system Node.
