Issues with reminder date/time selection

[v4hn]

Overall the dialog for selecting reminder times feels a bit raw compared to the overall very well-designed app.

To reproduce:

• Add a new recording
• tap "add a reminder"
• quirk 1: previous days can be selected, but reminders in the past don't make sense
• select any date and tap "ok"
• minor quirk 2: in dark mode the text of "ok" and "cancel" has very low contrast, especially when compared to the colorful background of the recording and the white numbers of the calendar
• either tap "cancel" on the time screen
• quirk 3: a reminder is added although you canceled the selection.
• or swipe to get back to last dialog
• quirk 4: you don't get back to the day selection, but the full recording screen and a reminder was added regardless
