applets/batterymonitor: clarify inhibition UI and list some more
We still get user complaints that this UI is confusing because of the terminology used and the visual proximity between the checkbox and the inhibitions list. This commit attempts to improve that by:
- Making the checkbox text shorter, have less jargon, and say the word "manual" in it instead of "automatic", which was confusing
- Adding the word "currently" to app-initiated inhibitions, to textually distinguish transient app-initiated inhibitions from user-initiated manual inhibition
- Separating the checkbox from the inhibitions list with a line
| Before | After | |
|---|---|---|
| One inhibition |  |
 |
| Multiple inhibitions |  |
