fix(recipes): preserve scroll position on filter, search, and folder-driven reloads

Five entry points that trigger recipe page reloads were not passing
preserveScroll: true, causing the page to snap back to top after
filtering, searching, or navigating folders — especially painful with
hundreds of recipes.

- RecipePageControls.resetAndReload() → refreshVirtualScroll() now
  passes { preserveScroll: true } (sidebar folder clicks/drag moves)
- FilterManager applyFilters/clearAllFilters → loadRecipes(true)
  changed to loadRecipes({ preserveScroll: true })
- SearchManager performSearch → loadRecipes(true) changed to
  loadRecipes({ preserveScroll: true })
- SettingsManager reloadContent → loadRecipes() changed to
  loadRecipes({ preserveScroll: true })

The normalizeLoadRecipesOptions boolean path always forces
preserveScroll: false — the object form is required to pass it.
