refactor(m0): restructure project and install dependencies

- Clean Avalonia template content (ViewLocator, greeting, empty Models folder)
- Add YKanBan.Tests (MSTest 4.4.1) to solution
- Install packages per plan version table (Semi.Avalonia, Lucide icons,
  Microsoft.Data.Sqlite, Pidgin, Newtonsoft.Json 13.0.4 fallback)
