fix(fe): compress OG image and add explicit meta tags

[SiegfriedBz]

Summary

• Replace the 1.6MB PNG OpenGraph image with an optimized 133KB JPEG (quality 85, same 1200x634 dimensions)
• Add explicit images array with width, height, alt, and type to both openGraph and twitter metadata in the root layout

Context

Sharing the app URL on WhatsApp was not displaying the OG image preview. Two issues contributed:

• The original PNG (1,582KB) exceeded WhatsApp's crawler timeout/size limits.
• The metadata relied solely on Next.js file-based convention without explicit image dimensions, which WhatsApp needs to decide whether to render the preview.
