Enhance debug logging for Passkey Registration requests

Improve logging in the register-passkey-options and log-requests middleware to provide detailed insights into request handling. Add user-agent analysis, IP address logging, and mobile/desktop detection to aid in troubleshooting. This update aims to enhance the clarity of request logs and support better debugging during the Passkey registration process.
