fix: FBX take name actually works (was still 'Armature|Scene' after the last attempt)

Browse Source 
The previous fix renamed the baked ACTION, but Blender's FBX exporter builds the
AnimStack name from scene.name (io_scene_fbx/export_fbx_bin.py), so every clip
still exported the take 'Scene' -> imported back as 'Armature|Scene'. Verified
failing on wan_dig_t3.fbx, which was built AFTER that commit.

Now sets bpy.context.scene.name = name before export. Both stated acceptances pass:
  strings clips_out/wan_dig_t3.fbx | grep wan_dig_t3  -> 6 hits
  Blender import                                       -> 'Armature|wan_dig_t3'
Re-exported wan_walk_t1 + wan_dig_t3; takes are distinct, so they can no longer
collide in the 24-track female_game bank.
