Fix SD card integration and Lua game loading

Browse Source 
- Fix SD card MISO pin (was using display MISO instead of SD MISO)
- Add FatFS mounting after SD card initialization
- Restore SPI baudrate on all SD init failure paths
- Add case-insensitive .lua file extension check
- Filter out hidden 8.3 filename entries
- Add SPI speed management functions for shared SPI bus
- Wrap all FatFS operations with SPI speed switching
- Restore display SPI speed (32 MHz) after SD operations
- Add debug output to Lua game loader

This fixes slow display refresh when SD card is present and enables
reliable Lua game loading from SD card /games directory.
