fix(updates): post-install grid is empty when view filter is "All Packages"

After installing a package, the grid was getting rebuilt with only the
upgradable list (the fast `/api/os-updates/packages` path), even when the
user had the view-filter dropdown set to "All Packages". In that state
the just-installed package never appeared — the grid showed "No packages
found" until the user manually switched view+back to retrigger the
full-list fetch. Reproduced by installing a package (e.g. `btop`) from
the "Install Package" modal while All Packages was selected.

Read the current filter before kicking the reload, and after
`loadInstalledPackages()` returns, also call `loadAllInstalledPackages()`
when the active filter is "all" so the newly-installed package shows up
without manual intervention.
