docs(wiki): catch-up sweep — five pages lagging the log

rongta-printer still named the cashino driver id (→ escpos + migration
0023 note); tariff-time-tiers listed the composer price preview as
deferred (→ delivered by the lab fee breakdown); tariff.md lab section
gained the breakdown + composer increment-guard paragraph; i18n.md now
records the "25 Qer 14:30" date standard + never-toLocaleString-for-
dates rule; fleet-deployment-komodo gained the park-lab stack + tier
table (the park-lab addition had also slipped the log — both fixed).

+## UI-wide date standard — "25 Qer 14:30" (2026-07-06)
+
+Dates were a mix of catalog-formatted "25 Qershor 20:01" and browser-locale "7/6/2026, 9:34 AM"
+(raw `toLocaleString` in ~20 call sites) — operator called it out. The standard now: **short
+month from the catalog** (`common.monthsShort`: Jan/Shk/…/Qer/Korr/…/Dhj), **24h clock**, year
+only when ≠ current. Helpers in `lib/format.ts`: `formatDate` ("25 Qer"), `formatDateTime`
+("25 Qer 14:30", optional seconds — the event-detail modal keeps them), `formatClock` ("HH:mm");
+`formatRelativeDateTime` keeps Sot/Dje and uses the same short months beyond that. Rule for new
+code: **never call `toLocale*String` for a DATE** — catalog months exist because the appliance
+browser's ICU may lack Albanian data; number formatting (thousand separators on money) still uses
+the locale. Swept everywhere 2026-07-06.
