Refresh Applications tab screenshots and reorder docs to match the app (#4903)

* Update Applications tab screenshots

Replace outdated install/uninstall/show-installed screenshots and add
new ones for upgrade-all, clear-selection, selected-apps counter, and
collapse/expand categories.

* Update Applications guide with new screenshots and sections

Point each tab at its refreshed screenshot, reorder tabs to match the
sidebar button order in the app, and document the Upgrade All,
Selected Apps counter, and Collapse/Expand Categories controls.

* Add missing Updates tab screenshot

The image was referenced by the Updates guide but was never checked
into the repo.

* Reorder screenshots to follow their intro paragraph

Move the tab screenshot below the introductory text on the Tweaks and
Updates guide pages, matching the paragraph-then-screenshot layout
used elsewhere in the docs.

 Use the Applications tab to install, upgrade, uninstall, and review supported apps from one place. WinUtil relies on package manager support for these actions, so the available results depend on what WinGet can detect and manage on your system.
