Add missing keys for en-US translations

- Updated power supplies to use identifyLed key
- Updated system store identify LED toasts
- Corrected DHCP key capitilization
- Did not make changes to factory reset modal keys,
they are being used dynamically with `${}` in the key.
Same for Power restore policy `$t{powerState}`
