Subject: [PATCH] fix(editor): auto-switch to structure phase when interacting
 with nodes in floorplan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two fixes for stair selection in 2D floorplan not working:

1. floorplan-panel: remove level > 0 restriction on auto-switch to structure
   phase. When viewing ANY level in the floorplan while in site phase, auto-enter
   structure mode so structural nodes (stairs, walls, slabs) become selectable.

2. selection-manager: expand auto-switch to also cover site phase. Clicking a
   structural or furnish element now auto-switches from site → structure/furnish,
   just like it already did between structure ↔ furnish ↔ zones.

This fixes the issue where stairs couldn't be selected in 2D and the floating
action menu (move/duplicate/delete) wouldn't appear.
