fix: add missing header declarations and editor scroll fixes

- mainwindow.h: add m_viewBtnGroup, m_btnReclass, m_btnRendered members,
  syncViewButtons() declaration, QButtonGroup/QPushButton includes,
  remove applyTabWidgetStyle() declaration
- editor.cpp: reset xOffset on applyDocument, clamp in restoreViewState
- test_editor.cpp: add horizontal scroll reset test

 This tool helps you inspect raw bytes and interpret them as types (structs, arrays, primitives, pointers, padding) instead of just hex. It is essentially a debugging tool for figuring out unknown data structures either runtime or from some static source.
