installed/blacklist: add sort & filter sheet + dedicated list item [1/2]

Share a sort/filter sheet between InstalledScreen and BlacklistScreen via
new commons module (SortFilterState + SortFilterSheet + applyFilter/applySort
on InstalledAppMeta), persisted per-screen. InstalledScreen renders a new
InstalledAppListItem that surfaces size, last-update, and installer instead
of Play-listing extras. Blacklisted rows now desaturate their icons.
