The setting previously used "numeric" and "alphanumeric" as its allowed
values. Rename them to "classic" and "semantic" to better align with the
product terminology for the work package identifier modes.
Includes a migration to update any stored setting values in the database,
updated constants and helper methods on Setting::WorkPackageIdentifier,
and all corresponding references across models, components, forms,
frontend controllers, locales, and specs.
