Function extract_dates_definitions

src/parser/classes.rs:723–754

Extract column names from the deprecated `$dates` property array. Before `$casts`, Laravel used `protected $dates = [...]` to mark columns as Carbon instances. Each column listed here should be typed as `\Carbon\Carbon` by the virtual member provider.

    members: impl Iterator<Item = &'a ClassLikeMember<'a>>,
