Reload titles on Games, show Home uploads' progress, reset the comfort form

From the independent review of this PR:

- Phones lost the Refresh button, and nothing else reloaded sideloaded titles,
  so one added or removed from another computer never showed. Opening Games
  now reloads them.
- Send files... on Home uploaded with its progress bar in the hidden Tools
  page, and phones have no Activity bar. Choosing files from Home now opens
  the file panel on Tools.
- A session that finished while the page was open left its settings (1 / 0 / 0
  after a test) in the form. The form goes back to its defaults when the
  session ends. The test now covers that, and its mock uses the page's real
  break default (20 minutes, not 30).
