Move strings to a single file

[AitorAlgorta]

Is your feature request related to a problem? Please describe.

All the strings are in the code and sometimes is difficult to find right string. Changing them or having multi-language becomes really difficult with this solution.

Describe the solution you'd like

Move all the string to a single file. And might be nice to use the useTranslations hook.
