fix(i18n): map cards and wind readout in the UI language; final review wording

A final review of both PDFs found text the earlier checks missed:

- Map cards: fire confidence (high/nominal/low) and age (24h), vessel
  types (TOWING, TANKER) and installation classes (BASE, AIRFIELD) showed
  in English. They now go through the catalog; the data stays English.
- The wind readout kept "10-14 14:00 UTC" and "29.93°N 97.74°W"; it now
  uses the locale's date, decimal separator and hemisphere letters.
- Catalog: one term per concept (label/подпись, basemap/подложка,
  PROVIDER CONTROLS, HEARD, zoom in, REGIONAL NEWS), calques and broken
  grammar in the scene editor, provider settings and Bhote Koshi notes,
  and Spanish wording that read wrong ("restringidas por el proveedor",
  "Incluye … no se incluyen", "justo ahora", "Sal").
