fix: wire up missing feature enforcement in relay

- Mirror channels now receive relayed messages (was blocked from sending but never sent to)
- Server allowlist enforced in relay (allowlist_servers gate check)
- Silent mode suppresses status broadcasts (_status respects 'silent' flag)
- Welcome message sent when channel joins via 'wh open'
