Part of milestone #6 (Selection and inspection). Depends on #78.

A HUD list of every placed building. The player can click a row to select the building, as an alternative to clicking it on the map.

Both lists follow the same rules, decided on 2026-09-30:

Clicking a row selects that entity (sets GameState.selected, from #78). It does not move the camera.
Only in NONE mode. In PLACE or DEMOLISH, clicks on the list are ignored and the list does not leave the mode (see #78 and #139). An accidental click on the list must not throw away an armed ghost.
Dimmed outside NONE. In PLACE or DEMOLISH the list is visibly inactive (lower opacity, or rows disabled), so the ignored click is clearly intentional.
Translucent over the map, but still catches the mouse. Translucency is only how it looks. The list's controls use mouse_filter = STOP, so a click on the list never reaches the map. PlacementController and DemolishController already skip frames where gui_get_hovered_control() is not null. Test this with a list row directly over a valid building site.
Follows the selection back. Selecting on the map highlights the matching row. Deselecting clears it. The row is a view of GameState.selected, not a second copy (the same principle as BuildingPanel following interaction_mode in #72).

Acceptance criteria

The list shows one row per placed building, with its type name and status (PLANNED, UNDER_CONSTRUCTION, BUILT, RUINED).
It updates on building_placed, building_removed and building_status_changed, with no polling.
In NONE, clicking a row sets GameState.selected to that building. The camera does not move.
In PLACE or DEMOLISH, clicking a row does nothing and the mode is unchanged. The list is dimmed.
Selecting a building on the map highlights its row. Deselecting clears the highlight.
A click on the list over a valid site never places or demolishes anything underneath it.
Unit tests cover selection from a row and the ignored click. A headed screenshot shows the list over the map.

Out of scope

Grouping by type or status, and filtering

Worker slot controls (#136)
