Nine more methods, so the registry owns 24 of 113.
The #858 privacy logic existed three times: PackingService had the primitives, the
controller layered emitToViewers and broadcastUpdate on top privately, and the
plugin deps factory carried a standalone copy of all four, with a comment asking
for them to be kept in lockstep by hand. Migrating packing meant either copying
them a fourth time or fixing that, so the two private controller methods moved
into PackingService and the factory copy is gone. Controller and PackingRpc now
call the same code, and the controller suite proves it by passing with all 45
assertions unchanged.
The four public/private transitions get one test each, because each one is a way
to leak a private item to the whole trip room, plus a test that the privacy is
read before the write rather than after: reading it afterwards would report
"already private", skip the room delete, and leave the item on every member's
screen.
