build: clear 295 -Woverloaded-virtual warnings in GUI widgets

Turns three hidden base virtuals into real overrides, clearing 295 of
the 553 -Woverloaded-virtual warnings and taking a full clang-cl build
from 1,264 to 969. Part of #15374.

Search.hpp: SearchDialog::Popup and SearchObjectDialog::Popup took a
wxPoint that neither body ever read, hiding the virtual
wxPopupTransientWindow::Popup(wxWindow*). Both bodies clear the input,
call the base, set focus and refill the list, and SearchObjectDialog
also guards re-entry, so hiding meant none of that ran when the window
was popped through a base pointer. They now override and forward focus.

LabeledStaticBox::SetFont and ScrolledWindow::SetBackgroundColour hid
their base virtuals the same way, so the label metrics recompute and
the child colour propagation only ran for callers holding the concrete
type. Both now override.

Marking a member override makes clang flag every other unmarked
override in the same class, so seven sibling declarations needed the
keyword too. Left unmarked they were worth 481 warnings, which would
have made this a net loss.

MSWDismissUnfocusedPopup is declared only inside #ifdef __WXMSW__ in
wx/popupwin.h, so off Windows there is no base virtual to override and
the keyword would not compile. Both the declarations and the definitions
are guarded, which is how wxWidgets itself declares MSWWindowProc in
wx/nativewin.h and how this repo already handles it in BBLTopbar,
MainFrame, Button, ComboBox and TabCtrl.

ScrolledWindow's constructor left m_userPanel and m_scroll_win
uninitialised unless the style requested a vertical scrollbar, while
SetBackgroundColour dereferences both. No caller hits that today since
every instantiation passes wxVSCROLL, but the override widens who can
reach them, so they are now initialised alongside their siblings.
