fix(copy): soundboard room/space wording, deafen Escape hint, pin typo; keep Reddit context= (#279, #280)

#279: Room Settings → Soundboard said clips are "inherited by every room
under this space" for plain rooms too; the wording now follows
room.isSpaceRoom(). The Push to Deafen description only mentions Escape
while rebinding. "can pin a messages" → "can pin a message".

#280: the tracking stripper removed Reddit's context=, which is what
makes a comment permalink show its parent comments. Only share_id and
rdt are stripped now.

Fixes #279
Fixes #280
