Summary by Sourcery

Consolidate task scheduling and error handling across utility and moderation cogs, switch RemindMe to use the centralized ReminderService instead of manual timers, simplify Wolfram cog loading based on configuration, and enhance TempBan and AFK loops with improved logging, error hooks, and clean shutdown.

Enhancements:

• RemindMe now validates and schedules reminders via the ReminderService and removes legacy on_ready scheduling code
• TempBan loop renamed and augmented with better logging, lock handling, error capturing, and Sentry integration
• AFK expiration loop renamed, adds before_loop and error handlers, and cancels on cog unload
• Wolfram cog loading moved to setup to skip loading when the API key is missing and initialization logging simplified

Reviewer's Guide

This PR refactors core utility and moderation cogs by replacing manual scheduling with a dedicated service, strengthening background task loops with better locking, logging, and error handling, and streamlining configuration-driven loading for the Wolfram cog.
