Rename NanoWidget to NanoSubWidget across widget headers

DPF deprecated 'NanoWidget' in favor of 'NanoSubWidget' during the
2020 -> 2026 timespan; the old name is now a deprecation-tagged
typedef alias. The override in tabview.hpp explicitly named the
base class to call setVisible, which triggered the warning every
build.

Replace 'NanoWidget' with 'NanoSubWidget' in tabview.hpp,
textview.hpp, scrollbar.hpp, label.hpp, and splash.hpp. No semantic
change — these are typedef-aliased to the same class. Just matches
upstream's current canonical name and silences the deprecation.
