Subject: [PATCH] UI: Rework constants for arcade-style layout and color
 palette

- Named color constants (arcade blue walls, golden coins, pink doors)
- Header bar layout with PAC-MAN title, score label, key indicator
- Sidebar time display with label and large value
- Game over and pause overlay positions
- Smaller round-looking coins (coin-size + coin-inset)
- Removed old magic position values
