Translate the dashboard to English; euro instead of lira

Dashboard: every label, empty state, chart legend and the login page
are English; numbers and dates use en-GB (24-hour clock, day-month
dates), money is EUR, percentages read 80% instead of %80, durations
"2 h 05 min". html lang is en. Server version 1.1.2; manifests pin it.

Car app: the charging tab's price suffix, validation message and total
cost use € instead of ₺.

Checked by rendering all three pages from the 1.1.2 image against
InfluxDB 2.7.12 in podman.
