fix: update contracts for hwepve 6th node + Mumuni migration (lxc/114 on hwepve)

- proxmox-monitor: 5→6 nodes, add hwepve (.4, Huawei Matebook 16), note Mumuni (lxc/114) placement
- zulip-health: add dual-gateway collision detection to B2, note Mumuni on hwepve
- hermes-agent-baseline: fix Mumuni node minipve→hwepve
- hermes-zulip-restore: add hwepve Proxmox column for Mumuni
- mumuni-delegation: fix CT 118/storepve/.6 → lxc/114/hwepve/.123, 5→6 nodes
- pm2-self-heal: verified — no Mumuni references, no changes needed

Post-migration discoveries:
- Mumuni container migrated from minipve to hwepve (6th node, 192.168.68.4)
- IP preserved (192.168.68.123), hostname 'mumuni' unchanged
- Dual gateway collision (PID 1442 --replace + PID 2924 --force) resolved by
  container restart at 10:07; gateway restarted clean at 13:06 with fresh Zulip
  queue (errors=0, reconnects=0)
