Fix AI model, Language/Country mapping, and Handsontable rendering

- GEMINI_MODEL for AI commands: gemini-2.0-flash-exp → gemini-3-flash-preview
- Language/Country: handle plain 2-letter codes (EN→Language, UK→Country)
  and "EN-UK" split format; previously only split format worked
- Handsontable black screen: add min-h-0 on flex-1 container so height:100%
  resolves correctly inside the flexbox chain
