feat: empaquetado .exe con instalador y fix conexion SCAII

- launcher.py reescrito para PyInstaller (Voila in-process, kernel router)
- build_exe.bat: script PyInstaller (onedir + collect-all dependencias Jupyter)
- build_installer.bat + installer.iss: instalador Inno Setup
- schema_registro_sqlite.sql: schema DataStage en SQLite
- _make_conn_str ahora respeta SCAII_TRUSTED (Windows Auth)
- .env.example: quitar variables DB_* (Postgres ya no usado por DataStage)
- requirements.txt: quitar psycopg2-binary
