After discussing it with the team, we now want to query all fields in
the table and the board by default. Feeding the cache with exhaustive
data will make the side panel's life easier, as it needs all the record
fields to determine the actions to enable.
This PR introduces a new Recoil state to store the flow.
A few parts of the application need to know the definition of the
current flow. Previously, we stored the workflow version's ID and
fetched its definition with the `useWorkflowVersion` hook. However, we
must use another strategy to visualize workflow runs. Indeed, we now
store the definition of the workflow in the workflow run output when it
is executed. This is useful for draft versions, which can change between
the moment they were executed and the moment they are visualized.
