[SQL Lab] Tab rename uses native browser prompt() instead of modal dialog

Bug description

When renaming a SQL Lab tab via the tab context menu, the application uses the browser's native prompt() dialog instead of a styled modal component consistent with the rest of the Superset UI.

The relevant code in SqlEditorTabHeader/index.tsx even has a TODO comment acknowledging this: // TODO: Replace native prompt with a proper modal dialog

Steps to reproduce

1. Open SQL Lab
2. Click the ⋮ (three dots) menu on any query tab
3. Click "Rename tab"
4. Observe the native browser prompt dialog appears

Expected behavior

A styled Superset modal dialog (using the existing Modal component) should appear, consistent with how other rename/edit operations work in the application.

Actual behavior

A native browser prompt() dialog appears. This cannot be styled, is blocked in some environments, and breaks the visual consistency of the app.

Environment

• Superset version: latest (master)
