Add support for 2.8" round TURZX USB display (PID 0x0028)

Register the 2.8" round panel (480x480, USB Product ID 0x0028) with the
existing TURZX USB comm class. This is the new-generation USB variant of
the 2.8" screen, distinct from the older UART-based 2.1"/2.8" models.

Changes:
- Add PID 0x0028 to the PRODUCT_ID table in lcd_comm_turing_usb.py
- Add a new size option in configure.py for the GUI dropdown
- Fix a latent bug in load_config_values where .replace() on size strings
  could produce corrupted values like '2.1" / 2.1" / 2.8"' due to
  substring matching — switched to equality checks instead
- Update README supported sizes list
