V398 STOCK NATIVE CHARACTER IMPORT/EXPORT

For an existing BG2 account setup, close BG2 and run:
  All Editors/RESTORE_NATIVE_IMPORT_EXPORT.bat
Choose the BG2 folder (containing BaldurII.exe).

This restores the engine's original CHARGEN_IMPORT, CHARACTER_EXPORT and CHARGEN_EXPORT menus and the normal Import button. No in-game Import/Export script, filename filter or filename-authorization action is used in these panels. It does not run the account setup or touch account records, saves or characters.

Character Export naming: type your account's first five letters plus two digits yourself (Drakh01, Drakh02, Krona01, etc.). Stock BG2 does NOT enforce this account name pattern or automatically choose an unused number; that would require custom code. The native CHR files live in the profile's characters/ folder. This change does not make nested characters/<accountname> directly accessible, does not remove the older account router service, and does not promise filesystem-level account isolation.

The existing SETUP_IN_GAME_ACCOUNTS.bat retains its filename and displayed version V398. Its source has been adapted so a future complete setup keeps stock Import/Export menus. Prefer the separate UI-only installer to avoid account flag resets.

The frozen V337 archive is preserved byte-for-byte. No automatic backup, save or CHR copy is created by this UI-only patch.
