Simplify login_tokens_test.go by using concrete sqlite.Store type Replace verbose inline interface declarations with sqlite.Store in setup functions and table-driven test fields. The test already depends on test_sqlite.New() which returns sqlite.Store, so the anonymous interfaces added no value and repeated the InsertUser/InsertLoginToken signatures four times. Also reuse insertTestUser helper in TestConsumeLoginToken_AlreadyUsed and TestReadUserByEmail, which previously inlined the same InsertUser call.
