Improve translations in UI (#1908)

- Trad mistake "Watt heure" on z2m integration (English language)
- Lan manager title more clearer than others
- In French langague, when you click on "Paramètres", the title of the window is "Réglages": it's not very coherent: I've fixed it.
- A save button was misspelled if you take the other buttons as an example.
- A few typing/translation errors have also been fixed in the MQTT integration.
