[IMP] web: list multi edition confirmation modal

Changed the information dipslayed by the confirmation modal in multi edition
in list views.

Before this commit, the modal simply showed a one-line message with the amount of valid records.

Now, there are 3 elements:
- If all of the fields cannot be changed, a first line warns the amount of valid records.
- A second (or first if all fields can be updated) line ensuring that the user is aware of
the occuring changes.
- A table displaying the affected field and the updated value (readonly widget with the new value).
