fix: persistent Tor channel messages, bulletproof Tor after deploys

- Messages persisted to disk (messages.json) — survive restarts
- Sent messages stored on backend via node-store-sent RPC
- Message deduplication (same pubkey + message within 30s)
- Max 200 messages in circular buffer
- Direction field (sent/received) for proper UI display
- Container doctor: prefer system Tor, remove archy-tor container
- Deploy torrc generator: read from tor-config/services.json,
  web apps map port 80→local port for clean .onion URLs
