Reorganize homepage: two divisions, Projects section, Fullum partner, project images

- Hero reworked to "Model. Optimize. Validate." with both-fields messaging
- Nav: Simulation / Optical Science / Projects / About / Contact
- New Projects section with 4 cards (GigaBIT, folded Newtonian, interferometer, polisher) using real card images
- Optiques Fullum as a standalone partner/collaboration block (not a project), with logo
- Optical Science: 6 uniform capability cards; emerald/teal palette across the site
- Tools updated to current Siemens naming (Designcenter, Simcenter 3D)
- Company About + legal name; optimization CTA; French page mirrored
- OIQ-safe wording throughout; no em dashes
