Testing Supabase code with supabase_test

Rules

• Test against a real client from testSupabaseClient, or initializeTestSupabase in a Flutter widget test. Never mock or subclass SupabaseClient, AuthClient or the query builders, and never subclass http.BaseClient for Supabase requests.
• Answer requests with the stub… methods of MockSupabaseHttpClient. Stub the rows the code under test should receive: filters are not evaluated.
• Put a client into a signed-in state with signInTestUser. Build auth payloads with testUserJson and testSessionResponseJson, and tokens with unsignedTestJwt. Never hand-assemble a JWT or session JSON.
• Assert on what was sent with requests and requestsTo, not by wrapping the client.
• Dispose every client at the end of the test.
• Match methods with HttpMethod.post and friends.
