Clean up issue comments, remove dead code, fix audit logger bugs

- Remove all 15 "Issue #XX" reference comments from production code
- Remove dead code: CooldownManager class (unused, using discord.py cooldown),
  is_owner() function (unreferenced), unused imports (datetime_time, get)
- Remove unused env vars: ANNOUNCEMENT_CHANNEL_ID, PELICAN_URL, HYTALE_SERVER_UUID
- Fix AuditLogger.flush() dropping items when queue > 10 (now processes in batches)
- Fix AuditLogger.log() using .seconds instead of .total_seconds() (broke after 1+ days)
- Use unicode escapes for emoji in poll reactions for consistency
