CRIOMAIN.CPP: translate Korean comments to English, clean UTF-8

Translated all EUC-KR/CP949 Korean developer comments (~35 lines) to
English. File re-saved as UTF-8 (was CP949/EUC-KR on disk).

Also included: g_dwRIOPollTimeout formula that scales WaitForMultipleObjects
timeout by baud rate: clamp(ceil(480000/baud), 5, 50) ms.

Key translations:
- Developer markers (sanghoon/hyun)
- Packet receive loop comments
- ACK/NAK handling comments
- Thread/COM init comments
- Button table comments
- Joystick pedal/throttle diagram comments

Decorative diamond markers (◆) stripped from case labels and section
dividers. Unicode arrows (← →) in diagram comments replaced with ASCII.
