Unification of need_charges_msg

[Uwuewsky]

Summary

None

Purpose of change

1. (off)'s

2. The game have many different messages for depleted batteries (need_charges_msg). The main issue is that these messages are too long and only appear in the activation menu, where screen space is limited.

Describe the solution

Replace all messages like The %s's batteries are dead with The batteries are dead. This wording is independent of the item's name, shorter, and more readable.

Minor related fixes:
Added the missing ammo_scale to shocktonfa, which prevented its flashlight from turning off when the battery died. Removed the unnecessary need_charges requirement, as turning the tonfa off does not require charge.
Laptops use the same messages for lighting up the screen.

Describe alternatives you've considered

Maybe a different message wording? It will display for both a depleted and a missing battery.
Maybe use the singular form The battery is dead.
