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).
