Value for radio not sent in hook/flow payload

[arladmin]

Describe the Bug

When creating a new item, if a Radio button's value is left unchanged (set to default), the payload in the Flow hook does not contain the field at all!

Related issue: https://github.com/directus/directus/issues/24660

To Reproduce

1. Set a default value on a Radio field in a collection
2. Create a Directus Flow, for action items.create for the particular collection
3. Create new Item for that collection. Do not change the Radio field's value at all.
4. The Flow payload does not consist of the Radio field at all

The expectation is: a 'configuration' (default value being set for a field) done entirely within Directus should get implemented properly (properly = work first-class throughout Directus), without having to take into account how the DB deals with it (because that's sort of the whole point of Directus) [as indicated in responses to other similar issues]
