refactor: single HTTP port, WebSocket proxy for LSP endpoints

- Remove static ports 2087/2088/2089 from Nomad; use one dynamic port
- pylsp and Bicep LS stay on localhost inside container (not exposed)
- aiohttp adds /python and /bicep WebSocket routes bridging to localhost LSPs
- Nomad env: HTTP_PORT=$NOMAD_PORT_http, internal ports fixed at 2087/2088
- Editors connect via ws://ilsp.i80.dk/python and ws://ilsp.i80.dk/bicep
- Traefik routes ilsp.i80.dk → single dynamic HTTP port
