Implement comprehensive BlueprintPasterTest suite

[tastybento]

Summary

• Replace 4 @Disabled("NMS Cannot be tested") placeholder tests with 25 real JUnit 5 tests
• Mock NMS by intercepting Util.getPasteHandler() via mockedUtil and new PasteHandlerImpl() via Mockito.mockConstruction
• Drive the BlueprintPaster state machine manually using a captured Runnable from the scheduler

Key fix

PasteHandler has a static initializer BlockData AIR_BLOCKDATA = Bukkit.createBlockData(Material.AIR). Since MockitoAnnotations.openMocks() runs before MockBukkit.mock() in CommonTestSetup, @Mock PasteHandler would fail with ExceptionInInitializerError. The fix is to create the mock manually after super.setUp().

Test coverage

Category	Tests
Constructors	clipboard, island, bedrock offset, Y clamping (max/min)
paste() basics	returns future, schedules timer, useNMS=false, owner messages, no-owner, null maps
State machine	all 7 states including overworld/nether/end dimension-done messages
Block/entity pasting	NMS paster vs fallback, entities message
Sink blueprint	getHighestBlockYAt() called when isSink() is true

Test plan

• ./gradlew test --tests "world.bentobox.bentobox.blueprints.BlueprintPasterTest" — 25/25 pass
• ./gradlew test — full suite passes
