* ICU-17235 fix(sql): add explicit casting to resolve Postgres 16 domain constraint changes
This migration updates the `wt_alias` and `wt_target_alias` domains to include explicit `::text` casting in their constraints. Postgres 16 enforces stricter domain checks, requiring explicit casts to ensure compatibility. These changes address upgrade issues by aligning the constraints with the stricter evaluation rules.
