Fix stair approach fall-through and relax steep slope climbing

Browse source 
Relaxed walkable slope threshold from 0.40 to 0.35 (~70° max) for
steeper stair climbing. Tightened WMO floor cache above-tolerance
back to 0.25 units to prevent cached stair landing from overriding
approach floor. Added M2 floor preference for ship decks to prevent
falling through to water below.
