Every edge answers a hover: tooltips for walls, doors, fire, illusions

Only the special door lock states carried titles. Now plain walls ('a
wall'), locked doors, the wall of fire (with its 4-damage warning), the
untested shimmer ('tap to test your eyes'), the known-illusion ghost,
and battle cracks (damage taken so far) all speak on hover. The
firewall's hover target is its bar; the flames stay click-through.
