fix(web): match usage titlebar text styling

[t3-code]

What Changed

• matched the desktop Usage title's size and foreground color to the shared titlebar styling used by new threads

Why

• keeps Usage consistent with the rest of the unified desktop chrome instead of rendering small, muted text

UI Changes

• desktop Usage now uses text-sm font-medium text-foreground
• visual capture is unavailable because the runner's X11 display was unreachable, so the real Electron app could not open

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes (runner X11 unavailable)
• I included a video for animation/interaction changes (not applicable)

Overview
On desktop (Electron), the Usage page title in the custom titlebar now uses text-sm font-medium text-foreground instead of smaller, muted styling (text-xs with text-muted-foreground/70).

That matches the non-Electron Usage header and the shared titlebar treatment used elsewhere in the workspace chrome.

Note

Fix Usage page titlebar text styling in Electron

Updates the <h1> title in UsagePage.tsx to use a larger font size and primary foreground color, removing tracking-wide and the muted/70 color that were previously applied in Electron's titlebar header.
