Add one-click install for favourite apps

Addresses #1508

Add an 'Install all' action to the Favourites screen that bulk-fetches
details and enqueues every installable favourite (skipping already
installed apps and paid apps anonymous accounts can't acquire), gated
behind a confirmation dialog that warns about per-app install prompts.

Show live state on each favourite row: an installed tick that updates
on install/uninstall events, and download/install progress mirroring the
Updates screen. Hide 'Install all' once every favourite is installed.

Treat only non-finished download statuses as in progress on both the
Favourites and Updates rows so a dismissed system install prompt no
longer leaves a row stuck showing 'Installing'.
