reconfirm that your bootloader is still unlocked if not the repeat the bootloader unlock
run the command below in adb window
Code:adb shell getprop ro.build.system_root_image
if the output of the above command is true, then use magisk manager to patch the AP file in your firmware (don't extract the boot.img, just select the entire AP file)
>flash the output patched file (if you're using odin, untick the auto reboot option)
>press power button + vol down to exit odin mode on the phone
>immediately the screen goes off, quickly press the keys to boot your device into recovery mode (you should know the right key combination for your device)
>in recovery mode, select factory reset data then select reboot system
>immediately press the key combination to boot to recovery mode again but this time, once you see the bootlogo, release all keys
>allow the device to boot (it'll take some time so wait patiently)
>if all goes well then you should see initial setup, setup the device and install magisk manager apk then launch it and confirm that magisk is installed
output of that command is false >>>
adb shell getprop ro.build.system_root_image

first, how did you verify that the bootloader is unlocked cause clearly the bootloader is rejecting the custom image you flashed into boot partition
second, i've check the boot and recovery.img files you posted in your OP, both of those files are not android images. ensure to upload the stock images you extracted from your firmware

ticking oem unlock in developer options doesn't mean that bootloader is unlock, run the command "fastboot getvar unlocked" to verify bootloader status
you need to check the files you uploaded cause they're neither boot nor recovery
download any hex editor tool e.g hxd editor
open the files using hxd, the header should be indicated as "ANDROID" if it's boot or recovery
the files you uploaded are some sort of MSdos program
