Widgets over builder methods

Prefer extracting UI into separate widget classes instead of _build* helper methods.

When a build method grows a non-trivial section, create a dedicated widget:

Private widget class (class _FooBar extends StatelessWidget) in the same file, after the main widget, or a public widget in its own file under components/ when reused.
Pass needed data via constructor parameters, not by capturing state fields.
_build* methods are allowed only for trivial one-liners; anything with its own layout or logic becomes a widget.

Benefits: const constructors, widget tree caching, no full-State rebuilds, State private members stay encapsulated.
