# What this PR does
- add user locale field to mobile app user settings table + add a test
that sends `PATCH` requests to this endpoint
- change "you're going on call" push notification text to include
localized shift time. The general format is now:
```python
f"You're going on call in {time_until_going_oncall} for schedule
{schedule.name}, {formatted_shift}"
```
- `time_until_going_oncall` is a "human-readable" format of the time
until the start)
- `schedule.name` is self-explanatory
- `formatted_shift` this depends on the shift. If the shift starts and
ends on the same day, the format will be "HH:mm - HH:mm". Otherwise, if
the shift starts and ends on different days, the format will be
"YYYY-MM-DD HH:mm - YYYY-MM-DD HH:mm". **Note** that all datetime
related formatting will use the new `locale` field that we are now
storing in the mobile app user settings table. If no locale is yet
present we will fallback to "en"
