feat(iot-hub): redesign item detail dialog, add installed item counts API

Redesign item detail dialog: move install/add/update/open buttons to footer,
move creator to sticky meta bar with avatar and verified badge, add manage
section with solution instructions, remove, and installed items count buttons,
update subtitle with grouped icon+text pairs matching design.

Add getInstalledItemCounts API (backend + frontend) returning item counts
by itemId per type. Replace installedDevices list with count-based tracking
in home, browse, and search components. Add installedItemsCount to item card
and detail dialog data flow.
