feat(firms): disable standalone broadcasts, use WFIGS renderer for growth

Browse source 
Disable all standalone FIRMS broadcast paths (cluster, halt, spotting)
by inserting early return None. Growth events now use the shared WFIGS
_render() for consistent multi-line format with movement data, and set
_severity_override=immediate + _cooldown_suffix for per-fire cooldown.
