Hendrik Liebau bb41cbd6ee Apply server actions transform to node_modules in route handlers (#89316) ...

The server actions transform, which handles the `'use cache'` directive,
was not being applied to `node_modules` when imported from route
handlers. This caused `'use cache'` functions from dependencies to fail
with errors like `"cacheLife() can only be called inside a 'use cache'
function"``.

The issue was that the `AppRoute` context used `internal_custom_rules`
for its foreign code module options, which did not include the server
actions transform. This is inconsistent with `AppRSC` (App Router
pages), which correctly uses `foreign_next_server_rules` that includes
the transform.

The fix extends `foreign_next_server_rules` with `internal_custom_rules`
and uses it for the foreign code context in `AppRoute`, matching the
pattern used by `AppRSC`.
