Update CI/CD: Use host build for GUI screenshots 
Replace the old Python-based gui_renderer.py with the new
host build system in the CI/CD workflow:

Changes:
- gui-screenshots job now runs 'make render_screens'
- Uses gcc (host compiler) instead of Python
- Renders actual source code with virtual LCD driver
- Updated gui-docs job for new screenshot categories

Benefits:
- Screenshots are rendered from actual project code
- Tests the lcd_driver.h API implementation
- Catches build errors in host_renderer.c
