Replace colored-rectangle world rendering with a proper tilemap system
using a 16x16 RPG tileset scaled 3x. Server generates terrain via seeded
procedural generation (river, ponds, dirt patches, tree decorations) and
sends it to clients. Client renders 3-layer Phaser tilemap with
8-neighbor autotiling for water/dirt edges.
