UX-46 review: Dutch wording fixes on the NL rows and notes

Text only. "stroom te opnemen" -> "stroom op te nemen"; Developer Tools is
"Ontwikkelhulpmiddelen" in HA and ui_text; the green stuck-meter row no longer
starts "Vastgelopen meter:"; maintenance banner names the phase in Dutch;
double "dan" in the device note; plainer peak reserve, peak guard, refused
commands and missing-entity wording. Two stale comments now say the banner
and Home bodies follow the page's language.
