feat(network+givc):

Updates:
- update flake inputs: givc, ctrl-panel

Changes to networking:
- auto-generate IP and MAC addresses
- remove 'debug' network from ghaf. We can simply remove
  the host from network in release and facilitate communication
  over mem share

Changes to givc:
- enable tls
- enable multiple admin service interfaces
- centralize givc-cli arguments across ghaf
