bug

fix(ios): use mobile mode for keyboard download pages

auto: increment beta version to 16.0.134

auto: increment master version to 17.0.32

This change refactors and cleans uninstall:

- rename methods to make it clear which ones are private/protected
- extract common code
- improve error reporting

This change addresses the code review comments, so that the
uninstallation tries to delete all three directories (keyboard,
documentation, font). It also adds the same logic to keyboards
installed in the User area.
