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.

+### Added
+- **Version footer** — a footer across the bottom of the window shows `RigDoctor v<version>` in
+  the bottom-right (moved out of the sidebar).
+### Fixed
+- **Pages scroll when content doesn't fit, and the window is no longer pinned to the tallest

+  like Uninstall are always reachable — and the window can now be resized smaller than the screen
+  (min height dropped from "taller than the screen" to ~600px). Pages that manage their own
+  scroll/fill (Dashboard, System Health, Inventory, Share) are unchanged.
