Fixed overrideFrequency Input Constraints (#801)

* Fixed overrideFrequency to properly allow for floats with a minimum of 410 MHz and maximum of 930 MHz. Added 3 decimal point check.

* Removed duplicate error message in FormInput.tsx

* Added error message for overrideFrequency in several locales

* Simplified check and reverted translated languages to English besides German. Also fixed a typo in src/components/UI/Input.tsx.

* Let i18n handle fallback + linting
