Rewrite: Next.js → ASP.NET Core 10 Razor Pages

Full rewrite of the portfolio site from Next.js 14 to .NET 10:

- ASP.NET Core 10 Razor Pages, no Node.js dependency
- EF Core 10 + SQLite (same schema as before — data survives upgrade)
- Cookie authentication (same single-password model)
- Resend contact form via HttpClient
- Bilingual FA/EN via locale cookie + BasePageModel
- All UI ported to Razor Pages with Tailwind CDN + custom CSS
- Vanilla JS: particles, typewriter, cursor, animations, portfolio modal
- Dockerfile: SDK 10.0-alpine → aspnet 10.0-alpine (no npm/Node needed)
- CI/CD: dropped NPM_TOKEN, ADMIN_SESSION_SECRET — pure dotnet publish
