style: use OVHcloud Design System standard colors

Map all presentation colors to official ODS tokens (ovh/design-system):
- Strip/accent: #0050d7 (ods-palette-blue-500 / primary)
- Text: #4d5592 (ods-color-text / twilight)
- Neutral: #666666 (ods-palette-gray-600)
- Heading/logo: #00185e (ods-palette-deep-sapphire)
- Links: primary-500 via --strip-color

Tool brand colors (Puppet/Ansible/Terraform) kept as-is.
