Analyze supplier part orientation during render

[seveibar]

Summary

• add an opt-in PartOrientationAnalysis render phase gated by platformConfig.enablePartOrientationAnalysis
• infer each component's authored, unrotated pin1_location, preserving an explicit Footprinter pin1location(...) declaration when present
• fetch supplier footprints through the configured PartsEngine and attach supplier_pin1_location_map metadata to pcb_component
• cache supplier analysis through localCacheEngine and deduplicate concurrent requests per PartsEngine
• correctly invert placed rotation and bottom-layer reflection before analyzing local footprint geometry
• use @tscircuit/circuit-json-util for canonical semantic pin 1 inference; no numeric rotation offsets or warning elements are introduced

Testing

• focused render test covers a rotated bottom-layer component, JLCPCB and PCBWay supplier metadata, persistent cache reuse, and a PCB snapshot
• bun test tests/components/normal-components/part-orientation-analysis.test.tsx
• bunx tsc --noEmit
• bun run build
• Biome check on changed files

Dependencies

• Add semantic pin 1 locations to PCB components circuit-json#684
• Add generic part orientation analysis platform config props#777
• Add semantic PCB pin 1 location analysis circuit-json-util#112
