fix(grub): fix bitmap error and menu rendering

- Convert bee-logo.png to RGBA (color type 6) and strip all metadata
  chunks (cHRM, bKGD, tIME, tEXt) that confuse GRUB's minimal PNG parser
- Move terminal_output gfxterm before insmod png / theme load so the
  theme initialises in an active gfxterm context
- Remove echo ASCII art banner from grub.cfg — with gfxterm active and
  no terminal_box in the theme, echo output renders over the menu area
- Fix icon_heigh typo → icon_height; increase item_height 16→20 with
  item_padding 0→2 for reliable text rendering in boot_menu
