bootBloomActive defaults true on every scene construction and bootDismissed
resets with it, but the only thing that cleared them was the secure EDGE. A
scene reload during an already-secure lock never moves `secure`, so nothing
cleared the bloom and the phone sat under a full-screen white overlay until the
shell was restarted. Casey hit it and reported it as "the hyprland error
screen"; `grim` returned a solid white 9KB frame, and hyprctl configerrors was
empty the whole time.
Third instance of this exact shape: locked_ack after a sessiond restart, the
ChargeRate stale-scene reload, and now this. Check the level at construction as
well as the edge.
Deliberately not a timeout — a bloom outliving its reason is a bug to locate.
