Align session verification logic with osu-web

Updated session verification method selection to match osu-web's State.php:36 logic, using SUPPORT_TOTP_VERIFICATION_VER for version checks and prioritizing TOTP when available. Added example environment files for osu-web-master to support local, dusk, and testing setups.
