Benign "error" msg cleanup

[goodboy]

There's a bunch in the info logging that can probably be tidied since a buncha new(er) users keep pointing it out..

• buncha widget complaints: QGraphicsGridLayout::itemAt: invalid row, column 3, 1 (from piker.ui._overlay.py) QGraphicsGridLayout::itemAt: invalid row, column 2, 2 QGraphicsScene::addItem: item has already been added to this scene (no idea where this is from still - needs to be hunted)

• the same pydantic model thinger we dealt with before in tractor i think? piker/piker/clearing/_ems.py:292: RuntimeWarning: fields may not start with an underscore, ignoring "_ems_entries" class Router(BaseModel):

• we have warn level shm stuff when creating new arrays but really this is expected behaviour, so maybe change these to info?
