feat(booth): payment receipt / exit voucher — transparency slip + CP852 fixes

After a completed payment the customer always gets a transparency record:
entry time, payment time, duration parked, amount + tender. One shared
ESC/POS renderer (renderReceipt + ReceiptData in @parking/devices), two
modes: VOUCHER = those figures PLUS the scannable Code128 barcode and an
emphasised walk-back-grace line, so the one slip both proves payment and
self-exits at a distant exit reader (replaced the old barcode-only voucher);
STANDALONE = detail-only, auto-printed at payment when no voucher is issued.
Figures fold from the SIGNED ledger (latest payment event); printed on the
booth printer (failover to dispenser). Best-effort: a printer fault never
blocks the exit that already happened — the modal shows a note and offers
"Reprint receipt".

Server: booth-print.ts printPaymentReceipt() + receiptFigures(); routes
POST /api/voucher (voucher) + new POST /api/receipt (standalone/reprint).
Both ESC/POS drivers gained printReceipt(). Web: BoothPayModal auto-prints
after a non-voucher payment + reprint button; api.ts printReceipt().

CP852 fixes found on a real printout: (1) uppercase Ë was mapped to 0xEB
(that's ű) — correct byte is 0xD3; (2) Intl.NumberFormat injects a NO-BREAK
SPACE (U+00A0/U+202F) that isn't in CP852 and printed as "?" — line() now
normalises it to a plain space ("1000 Lekë"); (3) grace line wrapped
mid-word — split into two short lines.

Full build green; both receipt modes render-verified; routes live.
