feat(gui): scrollable pages + version footer — 0.37.0

Wrap each page (except self-scrolling Dashboard/Health/Inventory and the Share
terminal) in a QScrollArea, so long pages scroll when too tall (Settings'
Uninstall is reachable again) and the window is no longer pinned to the tallest
page's height — min height drops from >screen to ~600px, so it can be resized
smaller. Add a bottom footer showing 'RigDoctor v<version>' bottom-right (moved
out of the sidebar); themed #Footer with a top border.
