Removed product search field, results list, barProductLookup(),
and selectProduct() from the bar view in index.html, bar.html,
app.js, and bar.js. Backend /products endpoints are unchanged.

Fix 1: Replace free-text staff name with a dropdown populated from staff.json
via GET/POST/DELETE /staff endpoints. Staff management panel on cashier page
(type name, Add button, chip list with × remove). Dropdown remembers last
selection per session via sessionStorage.
Fix 2: Split single-page app into /cashier (register + top-up + member list +
staff management) and /bar (charge only). Each page is its own HTML file
with two plain <a> nav links; / redirects to /cashier. Shared helpers
extracted to common.js; page logic in cashier.js and bar.js.
Fix 3: Statement view gains an A4/A5 radio toggle that rewrites a dynamic
<style> @page rule before the browser print dialog opens. Defaults to A4.
Fix 4: POST /topup and POST /charge now return entry_id. Each successful
transaction opens /receipt/{entry_id} in a new tab — server-rendered HTML
showing member name/number, type, amount, balance-after (computed as running
sum up to that entry), staff, note, timestamp. Same A4/A5 print toggle.
