fix(desktop): show tooltips on all statusbar item variants

[alelpoan]

What does this PR do?

Statusbar items (Terminal, YOLO, Gateway, Agents, Cron, version, timers) all had title strings defined in useStatusbarItems, but the title prop was never forwarded to the underlying HTML elements in StatusbarItemView. As a result, no tooltips appeared on hover making it hard to discover what each icon/button does without prior knowledge.
(e.g. the terminal toggle was undiscoverable without prior knowledge personally spent 20 minutes looking for it before finding it via the agent)

Duplicate of #43077 — both forward title={item.title} to the statusbar render paths in StatusbarItemView (apps/desktop/src/app/shell/statusbar-controls.tsx) to surface native hover tooltips. #43077 is the earliest still-open PR with the identical mechanism (also Fixes #43071). Related: #41967 (Radix-tooltip approach for the same items).
