feat(viz-platform): implement DMC 2.x component registry (#171)

- Add component_registry.py with version-locked registry loading
- Create dmc_2_5.json with 39 components for DMC 2.5.1/Mantine 7
- Add generate-dmc-registry.py script for future registry generation
- Update dependencies to DMC >=2.0.0 (installs 2.5.1)
- Includes prop validation with typo detection
