dave: skip input auto-focus on mobile, dismiss Done on focus queue nav

Don't request_focus() on the text input when is_compiled_as_mobile to
avoid the virtual keyboard popping up on every session switch.

Also auto-dismiss Done items from the focus queue when navigating
via next/prev (Ctrl+N/P or the mobile NEXT badge), matching the
session list behavior.
