fix: remove incorrect [weak self] from SwiftUI View closure

SwiftUI Views are structs (value types), not classes, so they cannot use
[weak self] capture lists. Removed the incorrect weak capture from the
linkAction closure in DashSpendTermsScreen.

This fixes the build error: "'weak' may only be applied to class and
class-bound protocol types, not 'DashSpendTermsScreen'"
