fix(blueprint): resolve UClass lookups so non-trivial parent_class & component_type work

[bwail]

Summary

Two longstanding bugs in HandleCreateBlueprint and HandleAddComponentToBlueprint (in EpicUnrealMCPBlueprintCommands.cpp) made the plugin silently incorrect for nearly every input:

Bug 1 — parent_class was effectively limited to Pawn / Actor

The handler prepends an A to the input then looks up /Script/Engine.A<Name>. UE runtime UClass names do not carry the C++ A/U prefix — the actual path is /Script/Engine.Character, not /Script/Engine.ACharacter. So parent_class="Character" (and anything not in the hardcoded short-circuit) silently fell back to AActor, with a warning logged about /Script/Engine.A<Name> not existing.

Bug 2 — component_type rejected every standard engine component

ComponentClass = FindObject<UClass>(nullptr, *ComponentType);

FindObject<UClass>(nullptr, BareName) only searches the transient package. Engine components live in /Script/Engine.*, so StaticMeshComponent, CameraComponent, PointLightComponent, BoxComponent all returned Unknown component type. The existing Component-suffix and U-prefix retries didn't help because the underlying lookup was still scoped wrong.

Fix

• Parent class: drop the A-prefix logic. Try /Script/Engine.<Bare>, /Script/Engine.A<Bare>, and the /Script/Game.* variants, then fall back to FindFirstObjectSafe<UClass> (UE 5.1+) for plugin/module-defined classes. Validate that the resolved class is Actor-derived.
• Component type: replace FindObject(nullptr, ...) with FindFirstObjectSafe<UClass> plus a full-path fallback via LoadObject<UClass>. Bare names like Camera, StaticMesh, PointLight, Box, full paths like /Script/Engine.SkeletalMeshComponent, and C++-prefixed UCameraComponent all resolve. Strips a leading U if the caller wrote it C++-style.

Both copies of the file (UnrealMCP/Source/... and FlopperamUnrealMCP/Plugins/UnrealMCP/Source/...) are kept in sync as before.

Verification

Tested on UE 5.7 against a Character-derived blueprint:

• create_blueprint(name="BP_FPSCharacter", parent_class="Character") → parent now correctly Character (was Actor)
• add_component_to_blueprint(component_type="CameraComponent", ...) → ✅ (was Unknown component type)
• add_component_to_blueprint(component_type="StaticMeshComponent", ...) → ✅
• add_component_to_blueprint(component_type="PointLightComponent", ...) → ✅
• add_component_to_blueprint(component_type="Box", ...) → ✅ (resolves to BoxComponent)
• Compile clean, transform/properties applied correctly.

No changes outside the two EpicUnrealMCPBlueprintCommands.cpp copies.
