feat: add verified role auto-grant cog

Summary

Adds a new Verified cog that automatically grants the Verified role whenever Logistics or Problem Writing is added to a member. Includes:

• on_member_update listener that detects trigger role additions, grants Verified, and looks up the audit log to identify who added the role
• Logs all grants to <#1471399531580100670> with member mention, trigger role name, and moderator info
• Hourly periodic sync loop that catches any members who have a trigger role but are missing Verified
• Enables intents.members (privileged intent) on the bot

Review & Testing Checklist for Human

• Privileged intent: intents.members = True requires the "Server Members Intent" toggle to be enabled in the Discord Developer Portal. If not already on, the bot will fail to connect after this change.
• Audit log attribute access: entry.changes.after.roles on line 63 may raise AttributeError if entry.changes.after is None or lacks a .roles attribute — the surrounding try/except only catches discord.Forbidden and discord.HTTPException, not AttributeError. Worth verifying against the discord.py docs or testing live.
• Verify hardcoded values: Confirm channel ID 1471399531580100670 and role names "Verified", "Logistics", "Problem Writing" match the actual server configuration exactly (case-sensitive).
• Live test: Deploy to a test environment or staging bot, add Logistics/Problem Writing to a member, and confirm (a) Verified is granted, (b) log message appears in the channel with correct moderator attribution, (c) periodic sync catches existing members missing Verified.
