Social: Adjust connection toggle UI and remove redundant "Preview" heading

[manzoorwanijk]

Fixes SOCIAL-350, SOCIAL-351

Proposed changes:

This PR improves the visual consistency of the Social Preview modal by adjusting the connection toggle styling and removing redundant UI elements.

Changes:

1. Remove redundant "Preview" heading: The "Preview" heading inside the preview section is now visually hidden (still accessible to screen readers) since it's redundant when the user has already clicked the "Preview" tab

2. Adjust connection toggle UI: Added background color (gray-100) to the connection toggle wrapper to visually connect it with the preview section below, creating a more cohesive appearance

3. Center align preview: Adjusted the styling for preview to make it always center-aligned - both vertically and horizontally.
