// Build a page controller wired to a working action and a navigation recorder.
// Both the New Post and Set Name pages extend PageController and take a single
// action dependency plus a navigate callback, so the wiring is identical; only
// the page-specific pieces differ. `cfg` supplies:
//   Page       - the page controller class (NewPostPage or SetNamePage)
//   Action     - the action class (MemoPost or MemoSetName)
//   actionKey  - the page's action dependency key ('memoPost' or 'memoSetName')
//   storeKey   - the action's store dependency key ('feed' or 'profiles')
//   storeFactory - () => a fresh store
//   pageDeps   - extra dependencies passed to the page constructor
