phase(N.4): WbMeshAdapter.Tick — drain WB pipeline queues per frame

Browse source 
Without this, ObjectMeshManager.StagedMeshData and
OpenGLGraphicsDevice._glThreadQueue grow unbounded as background
workers prep mesh data + queue GL actions. Visual stress test of
flag-on at radius 7 showed real FPS drop and rising frame latency
from this leak.

Tick() drains both queues:
1. _graphicsDevice.ProcessGLQueue() applies pending GL state.
2. Loop _meshManager.StagedMeshData.TryDequeue -> UploadMeshData
   to materialize VAO/VBO/IBO for each prepared mesh.

Wired into GameWindow's render loop before draw work begins.
No-op when adapter is uninitialized or disposed.

Pattern matches WB's reference ObjectRenderManagerBase.ProcessUploads
without the prioritization heuristics (we're not yet drawing the
results — Task 22's WbDrawDispatcher will add prioritization when
visual budget matters).
