Selecting multiple days and editing symptoms, the dialog title only shows one date

[carstenhag]

Describe the bug
We support editing symptoms for multiple days at the same time. But the date in the title only shows one date, which could mislead the user in thinking the symptoms will only be changed for that specific day.

To Reproduce

1. Select multiple days
2. Tap on Symptoms
3. Only the last-selected day's date is shown in the title.

Expected behavior
Unclear. Maybe don't include the date when there are multiple days selected? Maybe include the number of days instead?

Either we show all dates (might be weird if we have several dates), or we show a x-y (which might be weird if you have dates that are not in followed order).
OR, since we are only working on one month here, we could do dd/mm and skip year? Would save some space in the dialog I think?

The title could also (always) be "Edit Symptoms" or "Manage symptoms", without date.
