Fleet label overlaps Starbase/CSS label, making station info and selection difficult

When moving a fleet near a Starbase or the CSS, the fleet icon/label renders on top of the station, blocking the station visuals and its information panel/tooltip. This also makes the station hard to select by clicking; the player must double-click the center of the star system to select it. Player context indicates fleets docked at an ONI Starbase (x: -30, y: 30) and another fleet idle at ONI-3.

1. Move a fleet onto/overlapping a space station (Starbase or CSS) within a star system.
2. Try to view/read the station information and click the station to select it.

The station should remain visible and selectable even when a fleet is positioned near/over it, and the station information should not be blocked by fleet labels (proper z-ordering and/or click priority).
