feat: config-gated flat-scalar sea level (D-033, terrain-water task 04)

SeaLevelModel: "flat" (one scalar, SeaLevelValue) or "field" (the
legacy latitude Lerp 0.26..0.15). Only GetSeaLevel's body changes —
all nine call sites (crater carve target, both flood fills, biome
split, beach band, Capitol window, town filters, A* zero-point)
inherit the model automatically; no consumer re-tuning. Default:
flat 0.15, pinned in ServerConfig.json.
