refactor(devices): rename driver "cashino" → "escpos" (generic ESC/POS)

The reachability-only clone driver carried its first unit's vendor name,
which read as misleading in the setup UI once other clones (ICS/Xprinter
XP-K200L, verified 2026-07-06: no /prn_stat.htm) used it. It was always
the generic ESC/POS driver — now named so:

- printer-cashino.ts → printer-generic.ts; GenericEscposPrinter;
  id "escpos", label "Generic ESC/POS 80mm printer (Cashino,
  ICS/Xprinter…)".
- Migration 0023 rewrites stored devices.driver_id rows.
- The registry keeps a PERMANENT cashino→escpos alias so restored
  pre-rename backups still resolve instead of "unknown driver".

Prose mentions of the Cashino as physical hardware stay — it's a real,
verified-fit printer; only the driver identity stopped being vendor-named.
