Foundation for the multi-tenant migration: adds the Family table with a unique InviteCode, and a startup hook that bootstraps a single default family from the FamilyCode config when the table is empty. No behavior change yet — the table exists and is seeded but nothing reads it. Also fixes the backend test command in CLAUDE.md: dotnet test on the .NET 10 SDK with MTP rejects the --solution switch and positional project args, so we now use Push-Location + --project.
