feat(cvm): fix CVM MCP roundtrip - task creation, subscription, relay selection

- Move CVM server start before mint_health_start (avoids RAM fragmentation)
- Fix NIP-01 subscription: #p tag must be array not string
- Fix read loop: tolerate TLS timeouts, don't disconnect
- Reduce TLS timeout from 15s to 5s for faster event delivery
- Add WS frame logging for debugging
- Sign test events with board's nsec (--sec flag) for owner auth
- Change default CVM relay to nos.lol (forwards ephemeral kind 25910)
- MCP get_config and get_balance roundtrips confirmed working
- Unit tests pass (16/16)
