[FIX] web: handling of invalid formats in list views

Added handling of invalid format types in multiple edition in list views.

Before this commit, in multiple edition, a field that was edited with an invalid value format
(e.g. a numeric field receiving a string value) didn't trigger a field_changed and no prompt
was shown; the record was simply idle with an dirty value.

Now, the list controller also listents for set_dirty events and automatically triggers
an error modal + discards all changes when receiving one.
