📄 Description

Describe your changes

Follow-up to #5372, which added --disable-legacy-port to the standalone management binary and DisableLegacyManagementPort to server.Config, but did not expose it in the combined server's YAML config. The combined server therefore always starts the backward-compatibility gRPC listener on 0.0.0.0:33073 with no way to turn it off.

Because a failed bind of 33073 is fatal, this makes it impossible to run two combined servers on one host (e.g. two independent meshes for different user populations behind one reverse proxy), even though every other listener the combined server opens is configurable (listenAddress, metricsPort, healthcheckAddress, STUN).

This PR adds server.disableLegacyPort to the combined YAML config and passes it through to the management server. Default false, preserving current behavior.

Tested: built the image from combined/Dockerfile.multistage and ran it with a minimal config.

disableLegacyPort: false (and unset): running gRPC backward compatibility server: [::]:33073 is logged and 33073 is listening.
disableLegacyPort: true: no compat listener; only the configured ports (11480/11490/11491 in the test) are bound.
