test(e2e): increase timing budget for CI and assert repos before save

The LoadingScreen runs in a background thread and then fires a 1.5 s
set_timer before pushing DashboardScreen. On slow CI runners the combined
latency can exceed the previous 3 s (30x100 ms) polling budget, leaving
app.original_repo / app.forked_repo still None when Save is clicked. This
caused save_member() to raise RuntimeError, which was silently absorbed by
on_button_pressed, so the screen never transitioned to SaveLoadingScreen.

- Increase LoadingScreen poll budget to 5 s (50x100 ms)
- Increase SaveLoadingScreen poll budget to 5 s (50x100 ms)
- Assert app.original_repo and app.forked_repo are not None after
  DashboardScreen is reached, making the failure obvious if repos are
  not initialised in time
