Fix settings title readability with semi-transparent background

[roomote]

Summary

Fixed the settings title visibility issue by adding a semi-transparent background layer to the header.

Problem

The settings title was becoming unreadable when content scrolled underneath it, as the header had no background to separate it from the scrolling content below.

Solution

Added the following CSS classes to the settings header:

• bg-vscode-editor-background/95 - 95% opacity background using VSCode theme colors
• backdrop-blur-sm - Subtle blur effect for visual separation
• sticky top-0 z-10 - Keeps the header fixed at the top while scrolling

Changes

• Modified webview-ui/src/components/settings/SettingsView.tsx - Added background styling to TabHeader component

Testing

• All existing tests pass
• Linting checks pass
• Type checking passes

Visual Impact

The settings title now has a semi-transparent background that:

• Makes the title readable at all times
• Doesn't interfere with the content below
• Maintains visual consistency with VSCode's design language

Review complete. No issues found.

This is a clean, minimal fix that adds a semi-transparent background to the settings header for better readability when content scrolls underneath. The implementation correctly uses the project's Tailwind configuration with properly defined VSCode CSS variables.
