desktop: armazenar dados em pasta 'data' ao lado do executável (fallback AppData) e remover NSIS v2 inválido

- main.tsx: resolveDataDir usa executableDir/data quando possível; se falhar, cai para appLocalDataDir
- tauri.conf.json: remove bloco windows.nsis inválido no schema v2 para build passar

Objetivo: instalar dados fora do AppData (ex.: C:\Raven\data) quando o diretório de instalação permitir escrita.
