docs(tiles): each SSE doc comment sits above its own function

_sseFilterSessionId() and its doc comment landed between
_updateSseSubscription()'s doc comment and that function, so two doc
blocks sat back to back and _updateSseSubscription had none. Each block is
now above its own function; the moved one's em dash became a colon.
Comments only.
