feat(slicer): expand common machine profile settings

[jpapiez]

Summary

• expose common machine hardware, build-volume, firmware, retraction, motion-limit, and start/end G-code settings through friendly metadata-driven controls
• hydrate promoted MachineProfileDto values through one typed DTO-to-Orca adapter while preserving raw settings and untouched absent fields
• normalize edited Orca wire shapes, clean up equivalent aliases only after explicit edits, preserve non-rectangular bed polygons, and support accurate dirty/reset behavior
• expand the frontend worker profile contract and add focused adapter/modal coverage

Validation

• React production build
• 20 focused Vitest tests
• TypeScript typecheck
• ESLint
• Git whitespace check
