fix(copper-pour): add outline parameter and fallback to board outline

Two issues fixed:
1. TypeScript schema was missing the outline parameter entirely,
   so MCP clients couldn't send pour boundary points.
2. Python code read "points" key but schema defined "outline" key.

Now accepts "outline" (with "points" as fallback for backwards
compatibility). When no outline is provided, automatically uses
the board edge bounding box as the pour boundary.
