fix(kakuteh7-wing): fix BOARD_FLASH_SECTORS to protect param sectors

Set BOARD_FLASH_SECTORS to 13 so the bootloader does not erase the
parameter sectors (14 and 15) during firmware updates. Previously set
to 14 which allowed the bootloader to erase sector 14, potentially
wiping stored parameters.
