TransportManager decomposition: - Extract TransportClockSync: server clock offset, yaw flip detection, velocity bootstrap, client/server mode switching - Extract TransportAnimator: spline evaluation, Z clamping, orientation from server yaw or spline tangent - Slim TransportManager to thin orchestrator delegating to ClockSync and Animator; add pushTransform() helper to deduplicate WMO/M2 renderer calls - Remove legacy orientationFromSplineTangent (now uses CatmullRomSpline::orientationFromTangent) Entity path following upgrade: - Replace pathPoints_/pathSegDists_ linear lerp with std::optional<CatmullRomSpline> activeSpline_ - startMoveAlongPath builds SplineKeys with distance-proportional timing - updateMovement evaluates CatmullRomSpline for smooth Catmull-Rom interpolation matching server-side creature movement - Reset activeSpline_ on setPosition/startMoveTo to prevent stale state Tests: - Add test_transport_components (9 cases): ClockSync client/server/reverse modes, yaw flip detection, Animator position eval, server yaw, Z clamping - Link spline.cpp into test_entity for CatmullRomSpline dependency Signed-off-by: Pavel Okhlopkov <pavel.okhlopkov@flant.com>
