⬆️(docker) upgrade LiveKit server to v1.13.6

The compose stack referenced livekit/livekit-server without a tag,
which resolved to :latest. Docker doesn't re-resolve a mutable tag it
already holds locally, so images earlier than v1.12.0 crashed
on startup:

    could not parse config: yaml: unmarshal errors:
      line 20: field allow_restricted_peer_cidrs not found in
      type config.TURNConfig

LiveKit parses its config in strict mode, and allow_restricted_peer_cidrs
only exists since v1.12.0. The TURN block added in bd81c994 therefore
carried an minimum version which was not reflected.

The Tilt/Helm stack builds its own image from docker/livekit/Dockerfile
to inject the mkcert root CA, and that was still based on v1.9.4. Bump
it to the same version so both dev stacks run the same server.
