feat(recording): add mic indicators and fix misleading sink icon

Mic step now shows 󰍬 with green/dim coloring to indicate which mics
are actively in use (RUNNING state), with active mics sorted to top.

Changed sink inactive icon from 󰖁 (slashed speaker, reads as
"broken/muted") to 󰖀 (plain speaker, reads as "no streams right
now"). Active sinks still show 󰕾.
