🚫 Missing required board assets

This PR adds new board configuration(s). Required assets must already exist in github/armbian/armbian.github.io.
They are required by Armbian Imager to ensure all boards are displayed with proper images.

• Board images: board-images/<board>.png (1920x1080 px transparent)
• Vendor logos: board-vendor-logos/<vendor>-logo.png (512x512 px transparent)

Missing items

• ❌ Board image missing for photonicat2

  • Expected: board-images/photonicat2.png
  • Fix: add the file to armbian/armbian.github.io (folder board-images/)

• ❌ BOARD_VENDOR not found in config/boards/photonicat2.csc

  • Fix: add e.g. BOARD_VENDOR="radxa" (lowercase recommended)

Once the missing files are added (or a PR is opened in armbian/armbian.github.io), re-run this check.

I see a few things were changed from module to built-in. Is this necessary?
