Subject: [PATCH] Fix scroll/focus shift on htmx navigation

When htmx performs boosted navigation (full-page content swap), it
defaults to scrolling the viewport to show the new content via
scrollIntoViewOnBoost.

Combined with RT's menu expansion on htmx:afterSettle, this causes
the viewport to jump around unexpectedly after navigation.

This fix:
1. Disables htmx's automatic scrollIntoViewOnBoost behavior
2. Adds explicit scroll-to-top only for body-target swaps (boosted
   nav), not for widget/element reloads which should preserve
   scroll position
