add oval hole support

[rushabhcodes]

Summary

• add oval handling to the Hole primitive so it emits a pcb_hole with hole_shape: "oval"
• treat oval holes like other width/height hole shapes when computing PCB bounds
• add a focused regression test and PCB snapshot for <hole shape="oval" />

Why

@tscircuit/props already accepts shape="oval", and nearby code paths already understand oval holes, but lib/components/primitive-components/Hole.ts still fell through to the circular-hole branch. That meant oval holes were not emitted correctly from the primitive component itself.

Validation

• bunx tsc --noEmit
• bun test tests/components/primitive-components/hole-oval.test.tsx
• bun test tests/components/primitive-components/hole.test.tsx
• bun test tests/components/primitive-components/hole-pill.test.tsx
• bun test tests/components/primitive-components/hole-rect.test.tsx
