feat: VPN peer QR code UI, consolidate CI workflows

- Add vpn.create-peer, vpn.list-peers, vpn.remove-peer RPC methods
- Generate WireGuard config + QR code (SVG) for mobile device connection
- Add "Add Device" modal on Network page with QR scanner support
- Remove old build-iso.yml (replaced by build-iso-dev.yml)
- Remove container-tests.yml (tests run in dev workflow)
- Remove container orchestration tests from dev workflow (redundant)
