Kept new site compounds on dry land

I changed new site placement to check the whole rotated compound footprint, with a minimum height of 0.4 metres above sea level. This keeps an otherwise dry entrance from placing its buildings or approach in the water.

Existing saves retain their original coordinates. An old coastal site can still be tidal; this change deliberately does not move places the player has already explored. The clips illustrate a current site, while the placement claim is backed by the retained heightmap and four-family checks.
