Problem

SkyGrid runs on the network, but the lobby offered no way to reach it, so even the team had to connect by hand. It is not ready for every player yet, so a plain entry for everyone was not an option.

Solution

The navigator's server row now shows SkyGrid after Build, for players with titan.navigator.skygrid. Everyone else sees the menu as before. A click checks the permission again and sends the player to the SkyGrid server. With four servers the row stays centred, so Survival, Creative and Build move one slot to the left for players who see all of them.

Implements the navigator-skygrid OpenSpec change (#530).

Tests

Navigator unit tests cover the entry with and without the permission, the click and the centred row. The smoke tests pass.
