feat: project cover art with AI generation, branding rename, RBAC fix, computation graph

- Add DALL-E cover art generation for projects (Azure OpenAI + standard OpenAI)
- CoverArtSection component with generate/upload/remove/focus-point controls
- Client-side image compression (10MB input → WebP/JPEG, max 1920px)
- DALL-E settings in admin panel (deployment, endpoint, API key)
- MCP assistant tools for cover art (generate_project_cover, remove_project_cover)
- Rename "Planarchy" → "plANARCHY" across all UI-facing text (13 files)
- Fix hardcoded canEdit={true} on project detail page — now checks user role
- Computation graph visualization (2D/3D) for calculation rules
- OG image and OpenGraph metadata
