Type into any window: fake input when no text field is focused

- KWinFakeInput (org_kde_kwin_fake_input v6, offered by KWin to the
  input-method process): keysyms with real modifier keys held
- The KWin backend uses the input method in text fields and fake input
  everywhere else, so shortcuts, terminals and the desktop get keys
- Text rules (auto-capitalization, double-space) only apply in fields
- Always Show setting keeps the keyboard up without a text field

+- Works everywhere, not just in text fields: with none focused, keys reach the focused window like a hardware keyboard (shortcuts, terminals, the desktop); "Always Show" in ⚙ keeps it up
 - Letters follow the system keyboard layout; the globe key switches it
 - Auto-capitalization, double-space → ". " (both optional, ⚙ on the bottom bar), backspace repeat → word delete
