Subject: [PATCH] test: fix gamma default + localized home

Two tests asserted pre-refactor behavior:
- pen_config_test expected the old pressureGamma default of 1.0; it is
  now the natural curve (the pen-feel feature). Also assert the new
  eraser defaults.
- widget_test pumped HomeScreen without localization delegates, which
  the now-localized app bar requires. Provide the delegates.

Full suite: 258/258 pass.
