Remove table header background styling (v1.7.6)

Removed custom background colors from table headers to improve preview appearance and maintain consistency with normal theming.

## Changes
- Removed background-color from default theme table headers (was #f6f8fa)
- Removed dark theme table header background styling block
- Headers retain font-weight: 600 for visual distinction
- Table borders and alternating row colors remain intact

## User Request
User feedback: "remove the theming of table headers, it looks bad. Keep normal theming of preview"

- * Security Benefits:
- * - No direct access to Node.js APIs (fs, path, child_process, etc.)
- * - All IPC channels are explicitly whitelisted
- * - Prevents XSS from escalating to full system access
