Environment

• Elixir version (elixir -v): 1.19.0
• Phoenix version (mix deps): 1.8.2
• Operating system: Mac 15.7.2

Actual behavior

Using import Phoenix.VerifiedRoutes when building a test case/helper raises no warning or error. When you have any ~p routes in a test, they will cause a compiler error warning:

** (BadMapError) expected a map, got:

[]

(phoenix 1.8.2) lib/phoenix/verified_routes.ex:943: Phoenix.VerifiedRoutes.rewrite_path/4
(phoenix 1.8.2) lib/phoenix/verified_routes.ex:915: Phoenix.VerifiedRoutes.build_route/5
(phoenix 1.8.2) expanding macro: Phoenix.VerifiedRoutes.sigil_p/2

Expected behavior

The compiler should let you know the error is import/use not a BadMapError.
