fix: brick by brick and model placement work the way the client expects

Mapped from the 1.10.64 client and live captures (docs/BuildWorkflow.md).

Model placement (PropertyManagementComponent):
- A brick built model placed from the inventory spawned at the world origin
  with no rotation and without PlaceModelResponse/PreCreate, and was saved
  to properties_contents with ugc_id 0; it is now placed where the client
  put it, keeps its UGID and blueprint and is saved with them.
- Picking up, putting away and taking apart a brick built model gave it to
  MODELS_IN_BBB and then deleted it; every way off the property now puts it
  in MODELS (carried when picked up), as live, with its blueprint config.
  Taking a premade model apart no longer deletes it either.
- Placing and removing a model saves the property at once, so a crash or a
  disconnect before PropertyEditorEnd does not lose it.
- DoneArrangingWithItem only answers when something new is picked (not when
  leaving), with the subject as build area; SetBuildModeConfirmed's
  warnVisitors matches live.

Brick by brick (BrickByBrick):
- BBBLoadItemRequest moves the model to MODELS_IN_BBB keeping its id and
  fails cleanly when the player has no such model.
- MoveInventoryBatch moves bricks between BRICKS and BRICKS_IN_BBB (it was
  not handled, so the client and server disagreed until a relog).
- BBBSaveRequest uses up the opened models, places the new ones through the
  property, returns the bricks (or uses them with bbb_consume_bricks=1),
  clears the autosave and sends RequeryPropertyModels. Every save makes new
  ugc rows (is_optimized 0, so the UGC server processes them).
- Quick save: SetBBBAutosave is stored per character (bbb_autosave).
- UnUseBBBModel puts a model back on the property where it was when it came
  from there, otherwise back in MODELS.
- Leaving brick mode without a save, a disconnect or a crash: the autosave
  is rebuilt into models (RebuildBBBAutosaveMsg) or the opened models go
  back to MODELS. MODELS_IN_BBB is saved with the character now and loads
  into MODELS, BRICKS_IN_BBB into BRICKS.
