Waiting Chairs, Pawn Side-Facing, Podium Queue Gate, Spawn Collision Fix

The row of 6 waiting chairs by the podium (all facing east) and pawns gained real side/profile facing art (a visible single hand on the near arm) instead of only front/back. Movement direction now drives which way a walking pawn faces. A "podium gate" was added so a customer only becomes eligible to sit in a waiting chair after actually meeting the host at the podium, not before — closing off a way to skip the greeting. Newly spawned customers no longer overlap each other or the dumpster on arrival.

(progress/056-shipped-wide-baseline-full-layout.png — a full-canvas checkpoint taken the next day specifically because the folder was almost entirely narrow/cropped shots relative to actual iteration count, not tied to a specific feature — is the baseline this file's own Iteration 14 onward, below, picks up from. It's also what prompted the "periodic wide-shot checkpoint" rule now in ../AGENTS.md.)
