Convert tests from TestNG to JUnit 5

[evanchooly]

Summary

• Replace all TestNG annotations with JUnit 5 equivalents (@BeforeEach, @AfterEach, @BeforeAll, @AfterAll, @Disabled, @Tag, @DisplayName, @ParameterizedTest, @MethodSource)
• Swap assertEquals/assertNotEquals argument order from TestNG convention (actual, expected) to JUnit 5 convention (expected, actual)
• Convert @DataProvider methods to static Stream<Arguments> with Arguments.of(...) rows
• Wrap expectedExceptions test bodies in assertThrows() blocks
• Replace throw new SkipException(...) with Assumptions.assumeTrue(false, ...)
• Add @TestInstance(Lifecycle.PER_CLASS) to TemplatedTestBase so @AfterAll works on instance methods (annotation is @Inherited, covers all 261 subclasses)
• Update TemplatedTestBase.validateTestName() to read @DisplayName instead of TestNG's @Test.testName()
• Fix array equality: assertEquals(double[], double[], delta) → assertArrayEquals in DoubleMappingTest/FloatMappingTest
• Remove invalid class-level @Test annotations; add @Test to individual test methods where needed
• Update all pom.xml files: remove TestNG dependency, add JUnit Jupiter 5.11.4 + params
• Add <useModulePath>false</useModulePath> to maven-surefire-plugin

Test plan

• ./mvnw install -pl :morphia-core -DskipTests compiles cleanly
• ./mvnw test -pl :morphia-core -Dtest="TypesTest" passes (44 parameterized tests)
• ./mvnw install -pl :examples -DskipTests compiles cleanly
• ./mvnw install -pl :morphia-validation -DskipTests compiles cleanly
• ./mvnw install -pl :morphia-kotlin -DskipTests compiles cleanly
• Full test suite run against a MongoDB instance
