Set up YesChef.Api.UnitTests and YesChef.Api.IntegrationTests projects
running on TUnit + Microsoft.Testing.Platform. Integration tests use a
single Postgres 17 Testcontainer per session and clone a migrated
template database per test (`CREATE DATABASE … TEMPLATE …`) so tests
remain fully isolated and run in parallel without replaying migrations
each time.
Test-author DX is built around fluent entity builders, a TestDataFactory
for common scenarios, and a two-level base hierarchy
(IntegrationTest / AuthenticatedIntegrationTest) whose `[Before(Test)]`
hooks stand up the per-test database, app factory, default user, and
authenticated HttpClient — leaving each test body focused on the action
under test.
Adds src/backend/global.json to opt `dotnet test` into MTP mode on the
.NET 10 SDK, and updates CLAUDE.md with how to run the tests.
