Backend:
- New models: Tab, TabEntry, TabPayment (3 new tables)
- Tab: open|closed|forgiven, one open tab per customer enforced
- TabEntry: what went ON the tab (per-item snapshot with description)
- TabPayment: what came OFF the tab; balance = sum(entries) - sum(payments), never stored
- New router /api/tabs/:
- GET / — list open tabs (sorted by balance desc); ?tab_status= override
- GET /{id} — full tab detail with entries + payments
- POST / — open new tab for a customer (400 if one already exists)
- POST /{id}/entries — add entry directly (amount + description)
- POST /{id}/pay — record payment; validates amount <= balance
- POST /{id}/close — close tab (requires balance = 0)
- POST /{id}/forgive — write off remaining balance
- GET /customer/{customer_id} — all tabs for a customer (open first)
- POST /api/orders/{id}/items/{item_id}/tab:
- Requires order has a customer assigned
- Finds or auto-creates open tab for that customer
- Sets order_item.status = "tabbed" (new valid status value)
- Creates TabEntry with auto-generated description
- Broadcasts order_updated SSE event
- Migrations: CREATE TABLE IF NOT EXISTS for tabs, tab_entries, tab_payments
Frontend:
- TabsPage (/tabs): open tabs list sorted by balance; each card shows charges/payments
history, live balance, Πληρωμή modal (defaults to full balance), Κλείσιμο button
(only shown when balance=0), Χάρισμα Υπολοίπου with confirm modal + reason
- CustomersPage CustomerDetail: open tab banner showing balance + entry count
(appears between stats and contact info when customer has an open tab)
- OrderDetailPage: 📋 Καρτέλα button appears on active items when order has a customer;
tabbed items show a 📋 Καρτέλα badge; tabItem mutation calls /items/{id}/tab
- Sidebar: CreditCard icon for Καρτέλες (after Πελάτες)

Backend:
- New model: Customer (customers table) — name, nickname, phone, email, notes, is_active
- Order model: add customer_id nullable FK → customers
- New router: /api/customers/ — list (with ?search=), create, get, update, soft-delete,
GET /{id}/orders (visit history with totals)
- Each CustomerOut includes visit_count + total_spent (computed from closed/paid orders)
- PUT /api/orders/{id}/customer — assign or unassign a customer; manager-only;
validates customer is active; broadcasts order_updated SSE event
- GET /api/orders/{id} now returns customer_id, customer_name (with nickname), customer_phone
- Migration: CREATE TABLE customers + ALTER TABLE orders ADD COLUMN customer_id
Frontend:
- CustomersPage (/customers): searchable list (name/nickname/phone), avatar initials,
visit count + total_spent on each row; click → detail panel slides in showing stats
(visits, total spent, avg ticket), contact info, notes, full visit history
- OrderDetailPage: new Πελάτης card — shows assigned customer in blue if set;
for open orders shows "+ Ανάθεση πελάτη" button → inline search dropdown → assign;
Αφαίρεση button to unassign
- Sidebar: Users icon for Πελάτες (between Επαφές and Ρυθμίσεις)
