feat(shader): Add prepare_global_blur and high-DPI scaling support

- Add prepare_global_blur() method combining Deep Sea render + blur
- Add fb_scale parameter to setup_fbos() for high-DPI display support
- FBOs now created at scaled resolution (width * fb_scale, height * fb_scale)
- prepare_global_blur() auto-initializes FBOs if scale changes
- Add test_blur_pipeline_prepare_global_blur
- Add test_blur_pipeline_high_dpi_scaling
