fix: create networks as bridge instead of external

- Changed all networks from external: true to driver: bridge
- Fixes chicken-and-egg problem where networks must exist before stacks can start
- backup_net, ai_net, auth_net, cloud_net, coms_net, finance_net, home_auto_net, homepage_net, passman_net, tak_net, vc_net now created automatically
