Allow building placement during view rotation (with middle mouse button)

Description:
Currently, left-clicking to place a building is disabled while holding the Middle Mouse Button (MMB) to rotate the camera. This is frustrating because the cursor often drifts to a different tile during rotation. When you release MMB, the building "jumps" away from the spot you were just inspecting.
Proposed Change:
Enable the Left Mouse Button (LMB) to confirm placement even while MMB is still held down.
Benefit:
This allows players to orbit the building ghost, verify the alignment from any angle, and click to build the moment it looks correct—without losing the position due to cursor drift after releasing the camera controls.
P.S. Phrased this with an LLM to come across more clearly.
