ticket: site metadata header + scannable Albanian ticket; widen barcode

- site_config gains optional park identity (park_name, operator_name, nius,
  address, phone, email); additive Drizzle migration 0001. GET/PUT
  /api/site-config read/write the full config (PUT partial patch, admin only);
  SiteSettings + SetupWizard expose the fields.
- renderTicket() prints an Albanian header sourced from site_config, the
  all-numeric 13-digit ticket id (12 random + Luhn) as Code128, large digits,
  and a lost-ticket footer. CP852 codepage so ë/ç render.
- Widen the Code128 module width 2->3 and height 80->100 dots so the
  short-range "Simple" QR/barcode reader decodes reliably (was barely reading
  at module width 2 on the 80mm head).

+## [2026-06-16] build | Scannable ticket — QR + Code128 on the Rongta dispenser
+
+`renderTicket()` now emits the ticket id as a printer-generated QR (ESC/POS `GS ( k`, model 2, ECC M) AND a Code128 1D barcode (`GS k`, set B), plus the human-readable id. Three independently-readable forms so a dead reader is recoverable (imager / 1D laser / phone camera / hand-keyed). No image rendering, no new dependency. Phone-scan operator fallback deferred (reuses the existing dispatch path). See [[ticket-encoding]].
+
+## [2026-06-17] build | Ticket id -> all-numeric 13-digit (12 random + Luhn); barcode-only ticket
+
+Replaced the `T-<uuid>` ticket id with a 13-digit all-numeric code (12 crypto-random digits + Luhn check) in `newTicketId()` so ANY legacy 1D barcode scanner reads it and the operator can hand-key it on total reader failure. Random keeps the unguessable anti-fraud property; Luhn lets manual entry reject typos (`validateTicketCode()`). `renderTicket()` now prints a centered Code128 barcode, the code in large digits below, then the issue time — QR dropped (may return as an admin toggle for mobile users). NOT a schema change: `identity`/`sessions.id` are free-form text; legacy ids coexist. See [[ticket-encoding]].
+
+## [2026-06-17] build | Park metadata in site_config + ticket header
+
+Extended `site_config` (single-row) with optional park identity: `park_name`, `operator_name`, `vat_number`, `registration_number`, `address`, `phone`, `email` — all nullable text (Drizzle migration 0001, additive). `GET`/`PUT /api/site-config` now read/write the full config (PUT is a partial patch; admin only); `SiteSettings.tsx` gained the fields. `renderTicket()` prints a header (park name large or "PARKING", then operator/VAT/Reg/address, plus a "Lost ticket? <phone>" footer) sourced from `site_config` via `EntryFlow.#ticketHeader()`. Open: non-ASCII (accent) chars need a printer codepage. See [[site-metadata]], [[ticket-encoding]].
+
+## [2026-06-17] build | Ticket in Albanian; VAT->NIUS, drop registration; CP852 codepage
+
+Ticket header now prints in Albanian and uses NIUS instead of VAT. Renamed `site_config.vat_number` -> `nius` and DROPPED `registration_number` (regenerated migration 0001 in place; only the dev DB had it, so no migration debt; dev DB reset + re-migrated). `renderTicket()`: NIUS line (only if set), "Printuar më:" before the timestamp, "Keni humbur biletën? <phone>" footer; strings centralised in a `STR` table for future i18n. Added CP852 (Latin-2) codepage support (`ESC t 18` + a Unicode->CP852 `line()` encoder with ASCII fallback) so `ë`/`ç` render. Touched: schema, migration, routes/site.ts, web api.ts + SiteSettings.tsx, devices interfaces + printer-rongta.ts, entry-flow.ts. Byte-verified ë->0x89. See [[site-metadata]], [[ticket-encoding]].
