feat: normalize theme keys across Angular/React and improve language menu}
- Bump version to v2026.4.408 - Add fromShortKey/toShortKey helpers in Angular ThemeService to convert between Angular internal names (p3xrThemeDark) and short localStorage keys (dark), ensuring consistent storage format - Add normalizeThemeKey in React theme store to handle Angular-format keys read from localStorage, fixing cross-frontend theme sync - Remove resize listener from language menu in Layout.tsx and instead disable auto-focus behavior on the MUI Menu to prevent focus stealing - Add English strings for moveUp, moveDown, aiMaxTokens, and aiMaxTokensInfo labels - Update vite from 8.0.3 to 8.0.5
