Subject: [PATCH] [REF] *: adapt codebase to new RelationalModel

This commit adapts the code in addons w.r.t. the introduction of
the RelationalModel.

Main changes that were requested are:
 - record datapoints no longer always have an "id" key in their
 data (they still do if the id field is in the view), so we use
 record.resId instead
 - the new model is based on fined-grained reactivity, so several
 components that previously relied on onWillUpdateProps to update
 their internal state no longer worked. Typically, using the hook
 "observeRecord" is the way to go now.
 - specialdata are no longer handled in the model, so the components
 needing specialData can use the hook "useSpecialData"
 - more generally, all overrides of models (RelationalModel or
 KanbanModel) needed to be reworked.
