## Context
Prefill the FIELDS widget configuration in standard page layouts during
workspace creation, linking each widget to a dedicated view with
positioned fields organized into sections (via view field groups)
We wanted something very declarative (by manually setting position and
visibility of each field per standard object).
In this PR I've generated all the compute- utils via AI (😨) for
position/visibility, we'll probably want to confirm with the product
which ordering/visibility we want for each standard object but I feel
like this can be merged as it is since it's behind a feature flag and
this will unblock the work on the frontend
