fix: counter/voice-setup read config live + exclude bots from counter; drop quests/achievements/wiki from roadmap

- VoiceChannelManager: read trigger_channel_id/category_id live from ConfigRepository instead of caching at construction, so !voice-setup takes effect immediately without restart
- CounterManager: read channel_id/format live from config (same stale-cache fix); count members excluding bots
- CounterSetupPrefixCommand: use bot-excluding member count
- VoiceChannelManagerTest: lenient stubbing for live config reads
- TODO: remove quests, achievements, wiki from roadmap
