DiscordNewSessionHandler.ParseTimeInput used DateTimeStyles.AssumeUniversal, which interpreted user input as UTC. A user entering 15:00 got a session scheduled at 18:00 MSK after rendering. Align with Telegram behavior by treating input as Moscow time and converting to UTC before storage. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
