install: RAM config ini, selection menu, and silent Hekate 8GB step

- Read sd:/config/omninx/ram_config.ini [Ram] 8gb=0|1 when present;
  otherwise show 4 GB / 8 GB menu, write ini, same input as variant menu.
- Replace fuse-based DRAM autodetect for hekate_8gb.bin handling.
- Reprint installer top bar after RAM menu confirm.
