Initial build: WishNinja self-hosted gift wishlist manager

ASP.NET Core Blazor (.NET 10) + EF Core/SQLite + Identity. Features:
- Wishlists & items with local image storage (upload, clipboard paste,
  or URL fetched and stored locally)
- Owner-hidden claims (enforced at the query layer) to preserve surprises
- Admin-invite-only onboarding with email-based password resets
- All state under /data; ships as a single Docker image

Includes Dockerfile, docker-compose, Gitea Actions CI (test + push image),
Unraid template, and xUnit tests (claim privacy, invite lifecycle, image validation).
