Change default_value column for custom fields from varchar to text
A custom field can be of many types, including note. For a custom field that is a note, you may want to use a default value that is longer than 255 characters, but currently the default value is stored as a varchar(255). It would make sense to change this column to text, so that longer values can be entered.
In the custom fields UI, this field would be changed to a textarea when note is selected.
For us, the use case would be storing the content of a short waiver, so that the exact value of the waiver at the time of signing can be stored on the participant for an event, but I can imagine there may be other use cases.
Will submit PR if supported.
