refactor(ml,app-distribution): align namespaced firebase export with other packages

[mikehardy]

Description

Use FirebaseNamespacedExport instead of the manual Module intersection type.

This was noticed as an inconsistency in these two packages during migration debt analysis

Small refactor to align them with what I believe is best practice

Code Review

This pull request refactors the exported firebase types in the app-distribution and ml packages to use the generic FirebaseNamespacedExport type. A review comment points out that for the ml package, the fourth generic parameter (representing multi-app support) is incorrectly set to false instead of true, which should be corrected to match the module's actual configuration.
