Event and location titles can be too long in UI

[richardolsson]

Description

It's currently possible to enter very long event and location titles, and have them render in the CalendarDayView in a way that breaks the UI.

Steps to reproduce

1. Go to http://localhost:3000/organize/1/projects/1
2. Click "Create activity"
3. Click on "Create event"
4. In the new event, click the title to edit it
5. Enter a very long (maybe 300 characters) title
6. Click the location to pick a new one
7. Create a new location with a very long title and pick that one
8. Go to the calendar day view on the day of that event

Expected Behaviour

Title should be truncated to single line

Actual Behaviour

Title renders in full, breaking the layout

Screenshots (if you have any)

Proposed solutions

It can be argued that it should not be possible to even enter such long titles, and while there is a limit in the API, it's very big (I think 300 characters or 3000 characters). But even if you decide to add some max length to the title field in the UI, the day view still needs to handle long titles.
