Issues Fixed or Closed by This PR

• Language and Snap Click settings overlapped VIA's EEPROM data, so changing the language could wipe the keymap.
• Fn+J+Z factory reset and the Fn+Home+Right backlight test never triggered on C3 Pro.
• Adaptive NKRO key counters drifted after clear_keyboard(), leaving a 6-key limit until replug.
• set_suppressed_override_mods() set the wrong variables, so the report wasn't flagged as changed.
• One-shot mod changes didn't flag the report under adaptive NKRO.
• Factory test version string and device ID, raw HID fall-through, VIA RGB save, #pragma error, duplicate suspend call, OS toggle, Digital Rain brightness scaling.
• Version: ANSI RGB build now reports 1.0.2; other C3 Pro variants stay at 1.0.1.
